Now F(x) = sin(x)+cos(x)
Finding x such that F(x) = k. To change the function, open the code and modify the function F(x).
Choose [a,b] where F is continuous such that  F(a) > k, F(b) < k  or  F(a) < k, F(b) > k.
With "test" you find 10 values of F from a to b.
k =
  a = b =  

To change F open the Code and modify F(x)

Save by clicking here (with the right mouse button) the file on your computer
(change the name if you want, but leave ".htm").
At this point you can use it to solve other equations.
Just open the source code, edit F(x), and run "save".
You can repeat this several times.
