Hi Guys I want to solve the following equations in Matlab x=y*a+(yb)^c1, a,b, and c are constants...This equation define a curve; y.x=A2 , A=constant, this curve intersect the first one in one point is the solution this may be simplified to a*y^2+y^(1+c)*b^cA=0 Thanks Last edited by Naz Ar; June 3rd, 2017 at 11:35 PM.

Question: x=y*a+(yb)^c1 Solving for c: (yb)^c = x  ya c = LOG(x  ya) / LOG(yb) Do you understand that?

c is constant, but y and x are the variables The equation is solved using newton's method Thanks
