I have searched the forums but have been unable to find a specific solution to this:
I need to solve for the first solution (first zero) to:
tan(c)=((a+b)*c)/((c^2)-ab); rearranged to:
c=atan(((a+b)*c)/((c^2)-ab)
I have tried the formula node, RIdder's and NR zero finder. Any help would be much appreciated.
