See this example: f(x)=(x+sin(3*x))*exp(-3*x*I) g(x)=f(x).expand() integral(f(x)-g(x),(x,0,2*pi))
The answer is I*pi, but it should be 0. Many other examples (related to Fourier coefficients) give similar errors. For instance: f(x)=(x+cos(x))*exp(-x*I) g(x)=f(x).expand() integral(f(x)-g(x),(x,0,2*pi)) The answer is -pi, and it should be 0. It can be easily with sagemath 9.4 in https://sagecell.sagemath.org Thanks in advance, Yours, Juan Luis Varona -- You received this message because you are subscribed to the Google Groups "sage-support" group.
