Hello, Keith!
Use a graphing calculator to approximate the solutions to three decimal places.
Try graphing and
. . and locate their intersections.
I need to use the graphing calculator to approximate, to three decimal places,for the solutions to the homework problems I am working on, giving all the solutions possible.
Here are two of the even ones in the book.
cos(x)=2x^2
x=?
cos(x)=x^2/2
x=?
I would appreciate an example of any method to use so I can grasp this and finish my homework, so I can study for another class. This website is such a help, we are very fortunate to have a site like this to help us better understand the concepts we are being taught.
Thank you very much!!

Hello,
which calculator do you use?
1. Draw the graphs of
on your calculator.
2. Place the cursor on the intercept of both graphs.
3. You get indicated the x-value and the y-value of the intercept somewhere on the screen.
4. Use the zoom-in function of your calculator, until you've got the result as exact as you need it.
5. First attempt: A(-0.63, 0.81), B(0.63, 0.81)
