How to draw a 1+cos theta it a cardiod curve on calculator

Ad

Hello,

Press [MENU]. Highlight the [GRAPH] icon and press [EXE]. Press [F3:Type] then [F2: r=]. Enter you expression as 1+ cos(theta). If there are any functions Y=, delete them by highlighting each one and pressing [F2:Del][F1:Yes].

Press [F6:Draw]Your cardioid is drawn on the screen. This type of graph r=f(theta) is a polar graph.

Hope it helps.

You have several types of graphs

**Function graph**s

Y_1=f(x), Y1=3X^2-4, [X, T, Theta, n] key types**X**

**Polar graphs** r=F(theta), r=r_o*ln(theta). [X, T, Theta, n] types **Theta **

**Parametric graphs** X_1=f(T) and Y_1=g(T). [X.T, Theta, n] types **T**

Examples: X_1= cos(T). Y_1= 2(1--sin(T))

**Sequence graphs **u_n+1= f(u_n), [X,T,Theta,n] types **n**

Y_1=f(x), Y1=3X^2-4, [X, T, Theta, n] key types

Examples: X_1= cos(T). Y_1= 2(1--sin(T))

To calculate the Cosine of an angle, you first make sure that the angle unit on your calculator is set to the correct one (degree, or radian). After that it is all simple. Enter the angle value (50 degrees) then press the [COS] key. If you get an error then press the COS key followed by the angle value then press =.

Note if your calculator display Cos ( , with a left parenthesis, then you have to press COS first followed by the angle value and possibly the right parenthesis.

Note. The theta here is of no relevance.

That hardly seems possible. Try graphing the function y=x.

There are a few ways to draw curves on this calculator

**Drawing Relations**

There are some other relation you can draw X=, X>, X< , and the drawing of general conics.

I hope that the foregoing remarks help you sort out the problem you are having. If they fail to do that, I suggest that you read the manual that shipped with your Prizm.

**Drawing functions**

- Type is y=f(X), the [X,theta, T] key enters X when pressed

- Type POLAR r=f(theta), key [X,theta, T] enters theta w. pressed.

- Type PARAMETRIC, requires an X=f(T) and Y=g(T) functions

- Inequality graphing. You can also draw some functional inequalities such as y> 2X^2-3
- Dynamic graphing (graphs where some parameter may be changing)

There are some other relation you can draw X=, X>, X< , and the drawing of general conics.

I hope that the foregoing remarks help you sort out the problem you are having. If they fail to do that, I suggest that you read the manual that shipped with your Prizm.

- Select the GRAPH utility.
- In the screen that opens, make sure the graph type is set to function Y=.
- If not set to function, press F3:type and select it
- Highlight Function Y1=, and enter the function Y1=[SHIFT][COS][X,Theta, T] and press EXE.
- Press F6:Draw.
- Change Zoom or window dimension if necessary.

- Go to Main RUN screen.
- Press SHIFT MODE to enter SetUp.
- Use down Arrow to move highlight to the ANGLE line.
- Press F2 to set angle unit to Radian.

When drawing function graphs of type Y1=, the name of the independent variable should be X

For polar graphs r=.., the independent variable is theta, while for parametric graphs it is T

To enter the default independent variable, press the key marked [X,Theta, T] . It will type in the correct name.

- Turn calculator ON
- If you do not see icons press the [MENU] key.
- Use the arrow keys to move focus on the [RUN] icon.
- Press [EXE]
- In RUN screen press the [OPTN].
- After you press the down key once you highlight the line "Func Type"

The polar graph type is set by pressing F2:r=. In general r=f(theta). After the F2 key is pressed the Function type changes to r=

Now, if you press the MENU key and use arrows to focus on and select GRAPH, the function entry screen looks as in the picture below (without the 2cos(3theta))

After you enter the function (use the (X, theta, T) key below the [ALPHA] to enter the theta variable) press EXE to validate.

After drawing the r1=2cos(3theta) curve I opted to change the function to r1=2cos(5theta)

Press F6:Draw to draw the graph. Here is what you get.

Enjoy.

Hello,

**The e is the same, it is the exponential**. According to Euler's relation

**e^(i theta) = cos(theta) + i sin(theta),** where** i** is the imaginary unit.

When represented on the complex plane (x,iy) the point (cos(theta), sin(theta)) is at the extremity of a vector of length 1 and making an angle theta with the real axis.

In (plane) polar coordinates, a point is defined by the radius r, and the angle, theta, it makes with the x axis, measured in the trigonometric (counterclockwise) direction. It is structurally equaivalent to representing it in the complex plane as r*e^(i*theta). Since r is the measure ot is radius, and the theta is it argument (angle). The complex notation is used for its convenience when adding vectors (as is AC circuits)

That is the theory.

I am inserting a clipping from the book to show you how to convert between polar and rectangular coordinates.
