Your questions doesn't make sense to me: in the definite integral there, the "dummy" variable of integration is x and the upper limit on the definite integral is also x. hongyi.zhao at gmail.com wrote: > 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.
