I'm new to sympy and pouring through the documentation. I don't understand the "pattern" part of the argument to rewrite. The following portion of a session illustrates my question:
>>> f=sin(x)+cos(y)/gamma(z) >>> f.rewrite(exp) -I*(exp(I*x) - exp(-I*x))/2 + (exp(I*y)/2 + exp(-I*y)/2)/gamma(z) >>> f.rewrite(sin,exp) -I*(exp(I*x) - exp(-I*x))/2 + (exp(I*y)/2 + exp(-I*y)/2)/gamma(z) Why does rewrite(sin,exp) also rewrite the cos(...) part of the expression when it has been explicitly given "sin" as the pattern to rewrite?
