SOURCE: SIN COS TAN

The answer that you have received in actuality is correct. However, it is in exact form when the answer that you were looking for was an approximation (decimal form) answer. To achieve this all you have to do is hit the alpha button (the yellow button with a diamond in the center) and then enter which will give you your desired answer :-)

SOURCE: calculator won't graph right

try seeing if the mode is in radians or degrees, it must be in radians

Let me know if this works

SOURCE: Won't Graph Exponential Function

Ok, try these two things and you should be just fine.

1.) Check your range for your graph. It is possible that the range you are using isnt large enough to show the curve. Also try using Z-fit vs Z-st. These are options that your calculator will give you once the equation is graphed.

2.) Place a parenthesis around the 2x, make sure that you and the calculator are both using the same order of operations. This move mill ensure that the calculator will multiply the variable, x, by two and then do the exponential.

This should do it!

Happy Graphing!

Having gone over a month without a response to my query, I assume it was a matter of the angular mode setting

To enter powers of trigonometric functions you must enclose the functions in parentheses and then apply the exponent to the whole. For example X1t =(sin T)^3 , Y1t=(cos T)^3 will give you a shape similar to a rhombus with concave sides. The symbol ^syands for the operation of raising to a power. The key is the one with the caret symbol ^ , and it is wedged between the xsqure and EXIT keys (third row of keys).

As regards the cotangent, use the equivalent definition cot(X)=1/tan(X).

The trigonometric function [SIN],[COS] and [TAN] have inverse functions arc-sine, arc-cosine, and arc-tangent which are also implemented on scientific calculators. To access the inverse trigonometric functions you use the sequences [SHIFT][SIN], [SHIFT][COS] and [SHIFT][TAN]. The functions are marked on the body of the calculator as [SIN^-1], [COS^-1] and [TAN^-1].

When you use these functions, make sure that the angle unit is correctly set (as required by the problem you are solving) because the angle values returned are in the same unit as the one set.

The FX-115ES is somewhat different to other calculators you might know. The sequence of keys is more like writing up a calculation in a textbook, whereas for "normal" calculators operations are reversed in some places.

For example, with most calculators you would type 30 [sin] to calculate the sine function of 30 degrees, with the 115ES its [sin] 30 [=].

The 115ES has all the standard trigonometric functions:

For example, with most calculators you would type 30 [sin] to calculate the sine function of 30 degrees, with the 115ES its [sin] 30 [=].

The 115ES has all the standard trigonometric functions:

- Standard functions (sin, cos, tan), type the [sin], [cos] or [tan] key followed by the argument.
- Inverse trigonometric (sin?¹, cos?¹, tan?¹), type [SHIFT][sin], [SHIFT][cos] or [SHIFT][tan] followed by the argument.
- Hyperbolic functions (sinh, cosh, tanh), type [HYP][sin], [HYP][cos], or [HYP][tan] followed by the argument.
- and finally inverse hyperbolic (sinh?¹, cosh?¹, tanh?¹), its [SHIFT][HYP][sin], [SHIFT][HYP][cos], or [SHIFT][HYP][tan] followed by the argument.

Press the relevant function key [SIN],[COS],[TAN] followed by the angle value.

For inverse trigonometric functions [SIN^-1], COS^-1], or [TAN^-1], Press [SHIFT][SIN], [SHIFT][COS], or [SHIFT][TAN].

For other functions

sec(x)=1/cos(x)

csc(x)=1/sin(x)

cot(x)=1/tan(x)

When calculating trigonometric functions one must make sure that the angle unit the calculator is using is the correct one.

The trigonometric function evaluations depend on the angle unit you are using: degree, radian, grad

While cos(90 deg)= 0,

cos(90 rad )=cos(90* 180/pi degrees)= -.448073616

ALWAYS CHECK UNITS before using trigonometric functions or their inverse functions.

The inverse trigonometric function share each the same physical key with its direct function. The inverse trigonometric functions are accessed with the [SHIFT] key

[SHIFT] [SIN] accesses the arcsine

[SHIFT][COS] accesses the arccosine

and [SHIFT][TAN] the arctangent.

[SHIFT] [SIN] accesses the arcsine

[SHIFT][COS] accesses the arccosine

and [SHIFT][TAN] the arctangent.

- Turn calculator ON
- If you do not see several icons, press the [MENU] key.
- Use the arrow to highlight the Graph icon and press [EXE]
- On the screen that is displayed it says Graph Func Y=
- Highlight Y1= (if it is not already highlighted) and use right arroe to open the line for editing.
- Type [SIN][X,theta,T], screen displays sin X
- Press [EXE] to validate the function.
- The highlighting moves to the line Y2=, where you entere a second function if needed.
- If no other function is to be drawn, press [F6:Draw]
- A wavy curve will appear on screen.
- You may have to change windows dimensions to occupy most of screen.
- While curve is displayed press [SHIFT][F3:V-Window]
- You can use the soft menus at the bottom to change window dimensions

- INIT : initial dimensions (default)
- Trig ; trigonometric
- STD: standard
- or RCL to recall dimensions that you may have stored previously.

You can also choose you own values of the window dimension: You enter Xmin, Xmax,Ymin,Ymax. In this case Xmin must be less than Xmax, and Ymin less than Ymax..

After you select a preset set of dimensions or you enter your own, press [EXE]. You will get something like this. Do not worry if the axes labels do not show: they have to be configured to show.

You would press on the SIN key, "sin(" should come on the display, then enter the value, for example 3.5 or -1 so that the display shows

sin(3,5) or sin(-1) for example.

remember to close the sin with the ) on the end.

**sin(-1) = -0.841470985**

sin(3,5) or sin(-1) for example.

If you want the inverse trigonometric functions you access them with arccos [SHIFT] [COS] (cos^-1)

arcsin [SHIFT][SIN] (sin^-1)

actan [SHIFT][TAN] (tan^-1)

You have to know the**principal domain** for the inverse trigonometric functions (see any book on trigonometry) to understand the results.

Hope it helps.

Hello,

You have 3 keys for the main trigonometric functions: [SIN], [COS] and [TAN]

To use them correctly you must set the angle unit to the one your problem calls for.

Press [SIFT][MODE] [3:Deg] for degree, [4:Rad] for radian, [5:Grad] for grad. Dependig on angle unit chosen a small D, R, or G appears on the top of the screen.

If you need the inverse trigonometric functions arcsine, arccosine, arctangent, you access them by first pressing the [SHIFT] key

Thus

arcsine [SHIFT][SIN] (sin^-1)

arcosine [SHIFT][COS] (cos^-1)

arctangent [SHIFT][TAN] (tan^-1)

The syntax for the function is

[SIN] # [ ) ] [=]; [SIN] 30 [ ) ] [=] gives 0.5

[COS] # [ ) ] [=] [COS] 19 [ ) ] [=] gives 0.945518576

Note: if the argument of the functions are numbers, the right parenthesis is not necessary. But if the argument is an expression (with various operations) better put the parenthesis to make sure the calculator is performing as one wants it to.

By the way, there are no keys, or key combinations to calculate cotangent, cosecant, and secant, but you can use the definitions:

**cotangent (x) = 1/tan(x) Do not confuse it with tan^-1**

**cosecant(x) = 1/sin(x) Do not confuse it with sin^-1**

**secant(x) = 1/cos(x) Do not confuse it with cos^-1**

Hope it helps.
