Hi Jack, I find your bumper books really useful. A bumper book of differential equations would be quite good. You could provide boundary conditions with unknown constants, without any real life context. This will allow the practice of doing the math.

Really appreciate these videos sir. Legend.

[okellorichard]

Thanks. I understood your explanation Sir

[anystice]

in part b, how did integrating k in terms of t give kt as the answer? how does integrating a variable in terms of another variable work? thank you

[football..editsjr]

can the 1/square root h not integrate to ln(square root h) x derivative of root h ??

[helintaha]

Sir please answer how do you know whether to leave the k where It is when you are separating the variables
