Hello

Im trying to get maple to solve trigonomic equations in a specific interval but having trouble solving e.g. cos(t)=tan(t),t in [0;2 Pi].

I can solve for the general solutions with solve(cos(t)=tan(t),AllSolutions) and use isolve to specify the interval but this only works for some equations. Can piecewise be used in some way or have i missed a basic function in maple as with ti89 or ti inspire i can easily find the solutions?
