# Why isn't there a systematic way to integrate, like derivating?

Hello everyone,,

I've always wondered to myself this question. How come there are rules of derivation, but there are no rules of integration, but only strategies? Indeed, when integrating, we symplify an expression to ultimately come to the point where we can ''break'' the integral by ''guessing what function once derivated would make this function'', but we do not have a systematic way of solving integrals like derivatives. Is there mathematical reasons, a proof for this? Have we just not find the ''integration rules'' or is it proved that they do not exist, that they cannot exist?

Thank you!

I don't understand your problem very well. Can you describe it more clearly?
