Question about Sentry CA 756 Calculator

Look for a key y= (y= editor). type in the right side of the function sin(x), press Draw or graph. After a graph is drawn, and if it is not well centred play with the Windows dimensions, or the Zoom functions.

There is nothing mysterious about it. Wittingly or not, you

switched the window limits.

**Examples**

Xmin=6.3, Xmax=-6.3

Ymin=3, Ymax=-3

or some other combinations.

Here is the 1st case (Xmin=6.3, Xmax=-6.3, Ymin=-3, Ymax=3).

The traced point has positive x

Complete switch. The graph looks correct but as

you can see the traced point has positive x,

and negative y.

I did not think the calculator would be that tolerant.

There is nothing to convert, because if T is a real number so is 40sin(4000T).

40sin(4000T)=40abs(sin(4000T))*sign(sin(4000T))

where**abs()** is the absolute value of it argument, and sign(sin(4000T)) is positive or negative.

So in (radius, angle) polar coordinates

r= 40 abs(sin(4000T)),

theta =(0, or PI), depending on sign(sin(4000T))

If you are trying to graph parametric functions, this calculator does not do graphs, and you need another function of T

40sin(4000T)=40abs(sin(4000T))*sign(sin(4000T))

where

Make sure you have the angular mode set to radians. In degree, the graph of sine(x) is nearly a straight line for small values of x.

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).

Set Zoom to Standard Zoom Std or arrange windows limit as follows

Ymin=-1.2

Ymax=1.2

As to Xmin and Xmax it depends on the angle unit. It would be best for you to use Radians. In that case you can set Xmin=-Pi and Xmax=Pi.

If you are using degrees as angle unit, you must set Xmin=-180 and Xmax=180 to get the sine but you will not be able to see much of the 0.5X function because it will shoot out off the graph.

My unsollicited advice is to use the radian as unit

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

Sep 20, 2010 | Texas Instruments TI-84 Plus Calculator

You have your angular mode set to degrees. Ten degrees is about 0.17 radians, and for small x: sin(x) is nearly equal to x. Thus, sin(x) from -10 to 10 is indeed nearly a straight diagonal line.

Press MODE, then scroll down to "Angle" to change the angular mode.

Hello,

Clear all ram

[2nd][MEM][7:Reset][1:All Ram].

To enter a function to graph ex: Y1=sin(x)

Press function key [Y=].

On first line where i says Y1= , enter the function [SIN][X,T,theta,n][)][ENTER]

Then press [GRAPH]

If graph is too flat adjust the window by pressing [WINDOW] and hoose different values for Xmin, Xmax, Ymin,Ymax.

Hope it helps.
