I need to find an x-intercept for this trigonometric equation, f(x)=(x/2)-sin(x). I already know that one of the intercepts in (0,0) because that is a y-intercept. I figure i could use Newton's method but this problem is in a section before Newton's method is introduced.
The Attempt at a Solution
I figured that the relation (sin(x)/x)=1 could possible be useful at first but now I know it's not. I know it has to be just one or two steps also. Help appreciated.
