# Solving for C in a function

Posted 10 years ago
 Been looking everywhere on how to solve for C in the given function. y(x)=Tan(X^3+C), y(0)=1. Below is my code or at least what I could come up with in the last few days. Any help would be much appreciated. Don't really need the answer but a push in the right direction. Clear[y, x] x0 = 0 y0 = 1 eqn1[x_, C_] = Tan[x^3 + C] cSoln = Solve[eqn1[x0, C] == y0, C]

 By the way, note that C is a Protected System symbol in Mathematica. It is a good practice not to use symbols beginning in an upper case letter or your symbols. Also, if when you first type a symbol it is colored black rather than blue, then it is something that is already defined in some way. ?C C[i] is the default form for the ith parameter or constant generated in representing the results of various symbolic computations.

 C [Element] Integers && C == [Pi]/4 + [Pi] CIs this Mathematica's way of saying C = Pi/4 ? Thanks for the reply!
