I have three problems that I'm having a hard time with. I'd appreciate any help with
any of the three problems.
[tex]\int(x^3 * sqrt(x^2 - 1)[/tex]
Solve for y (separation of variables):
dy/dx = ((2y + 3)^2)/((4x + 5)^2)
Separation of variables for 3rd problem.
The Attempt at a Solution
I have work on scartch paper but I get stuck.
