  • Solving an ODE using separation of variables. I find the solution of a differential equation by splitting it, putting all the x terms on one side and all the t terms on the other side, and integrating. This gives an answer in implicit form, which sometimes we can write in explicit form. This is a very common technique taught in calculus classes.

    I think the exponential's sign is supposed to change when it gets moved from denominator to numerator at 1:33

    Dear Dr. Peyam! I love your videos! I would like to make a request: one or more videos on finding the exact part of differential forms. Wouldn"t that be cool? With topological considerations and all that 🙂

    So nice! How about “Matrix-th derivative of a matrix”?

    Thanks for clarity Dr Peyman 👍 ! As another reviewer has already written, normal law is not everywhere 😁
