How do you solve this. I need to find where x intercepts in these 2 graphs.
x^2 = cos(x)
I know the answer is .82 but how do you get it?
Solution
It is impossible to solve such equations by equating etc. The only approach is by plotting the
graph and approximating th value. The point where the graph intersects denotes that you get
same f(x) for an \'x\' . Hence the solution lies there. In my graph above , i drew the parabola and
cos x and found by approximation(like Binary Search) the values ti be PLUS 0.82 and MINUS
0.82.
