- Keep your function in Y1
- Set Y2 = (Y1)
^{2} - Turn off Y1 by placing
the cursor on its equal sign and pressing enter until it is not
highlighted.
- View your function in
Y2. Set the window values with Xmin = 0 and Xmax = 200, use
Zoom>ZoomFit to see your graph. Use CALC>
_{}to solve the integral.

OR

- Use MATH>fnInt(Y2,x,0,200).
Remember, Y2 is found under VARS>YVARS>Function>Y2.
- Remember to multiply
your final answer by π.
