I have my first ode test Wednesday. Been doing math for 12 hours. You and the organic chemist are the biggest help in the world.

this is literally the only video on youtube showcasing second order DEs with variable coefficients. bravo. you're not variablephobic, liked.

you do the best job when it comes to solving difficult problems, your examples are not easy as 1+1. I feel better prepared after seeing you solving this, now i will try myself. Thanks!

I didn't understand this topic in class, but after this video I think I can forever use the Reduction of order method to find the second solution without any doubts. Thank you so much, you also made this video exciting, short, and easy to understand.

Love your videos. Even older ones like this one

Also you're the first person in a while that I've seen write seven as " 7 " and not " -7- "

Thank you so much. It helps me a lot.Before this video, i have no idea about reduction of order but now i am pretty sure i know it.

Thanks man. This helped me a lot. What I would really like to see, Is one of these equations solved in various ways. So we can compare which way would be the best to use

hardest carry ever my prof couldn't explain shit about reduction of order but this video was so clear !

This is fantastic! If you let y1 be a solution to a second order homogeneous equation with variable coefficients in standard form, and work your way through this process it leads to a real neat formula you can use
