Hello! Why maxima doesn't solve the following equation? (%i1) solve(A*sin(x)+B*cos(x)=C,x); cos(x) B - C (%o1) [sin(x) = - ------------] A And how can I run maxima in debug mode so that I could see how lisp functions are called? And watch by steps how maxima tries to solve this equation for example? Semyon.
