Dear Mathgroup users, I've the following equations: \[\sin \left( \theta \right) = a{x^{^2}} + bx + c\] and \[y = \int_0^x {\tan } \left( \theta \right)dx\] I want to obtain the expression of y as the function of x. How should I write the code within mathematica? Thanks in advance. -- Hongyi Zhao <hongyi.zhao at gmail.com> Xinjiang Technical Institute of Physics and Chemistry Chinese Academy of Sciences GnuPG DSA: 0xD108493 2009-5-5
