What are the prereqs for differential equations? Do you need to know integral calculus too, and if so, to what extent? I want to learn about DE's as quick as possible but I'm not sure if I'm ready yet, my differential calculus is up to par I believe but my integral calculus is pretty weak, is that going to be a problem?

When solving DEs, we can often leave the integrals in the solutions unsimplified as simplifying the integrals are not the key points when solving DEs, but it doesn't mean than we can completely ignore integral calculus when solving DEs. Because some of the DEs must involve integral calculus to solving. For example:
So you have the freedom to completely ignore integral calculus when solving DEs, but you will become the disadvantages of solving some types of DEs.
