What topics of matan do you need to know in order to start studying difurs?

Question

Mathematics

Next semester, we start studying difurs. It's a problem with matan, but I can take derivatives and integrals.

Answer 1

Mathematics is not a science where "I teach here, I don't teach there." There are numerous internal connections.
Master the entire matan course that was given.

Answer 2

To be honest, it sounds strange "it's a problem with a matan, but I can take integrals." For all methods of integration should bounce off the teeth, this is a minimum, which means that you also need to understand the previous material, the meaning of the derivative, finding different limits, the banal form of elementary functions and trigonometry. In general, if it’s for credit somehow, then at least memorize the main methods (replacement of a variable, substitution under the sign of a differential, trigonometric, improper, in parts, fractional rational, trigonometric ...)
