1) Consider the differential equation

2y + dy/dx*tan(2x) = cos(2x) (π/4 < x < π/2)

Find the general solution of the differential equation, expressing y explicitly as a function of x. Hence find the particular solution of the differential equation that satisfies the initial condition y(π/4) = 1.

2) e^t dy/dt = y3 (0 < y)

Find the general solution of the differential equation, expressing y explicitly as a function of t. Hence find the particular solution of the differential equation that satisfies the initial condition y(0) = 1.
