Question about Casio FX-9750GPlus Calculator
Usually ypu know the equation then graph it. However in doing statistics, it may appear that the curve of best for a scatter plot could be could an exponential. In that case you use the STAT application to enter the x-data in List 1 and the y-data in List 2. When you finish press the f1 key to select Graph1. You should also verify by Pressing F6:set that the graph type is set to scatter, and that List 1 contains the x-data and List 2, the y-data. After you verify that all is in order press the F1: Graph 1 key.
As the graph is displayed you will see several tabs with various regression models. Pan thr tabs to the right to get to F2:EXP. Select it.
The equation is displayed on the next screen. At the bottom of the screen you see two tabs COPY and DRAW. Press f5:Copy to copy the equation in one of the y= functions.
Press Draw and you will see the curve of best fit superposed on the scatter plot points.

SOURCE: How do I graph an equation such as y= 5x + 2?
Hello,
Turn calculator ON. If you do not see several icons press [MENu].
Use arrow to select the [GRAPH] application and press [EXE].
In the entry screen, the line with Y1= is highlighted. If it is not, use arrow to highlight it.
Press the right arrow, the highlighting disappears leaving you with Y1= and the blinking cursor.
At the position of the cursor enter 5 [X, theta,T] key under the [ALPHA]. On the screen appears 5X, complete you equation +2.
Press [EXE] to store function.
If you want to draw other functions, it is time to do so on that screen.
When done press [F6:Draw}.
If the screen does not show a lot of the function, you can use the arrow keys to pan the graph.
You can also press [SHIFT][V-Window] to set the window limits.
Hope it helps.

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).
