Can some one please solve these problems for me (Separable Differntial Equations), I'm stuck on the solving part.
Problem 1: dy/dx = -4x^3y^2Solve for the particular solution y=f(x) to the given differential equation, with the initial condition f(0)=1.8. Then find and report, to five places after the decimal, f(3). ( Do not round)
Problem 2: dy/dx=ytanx Solve for the particular solution y=f(x) to the given differential equation, with the initial condition f(0)=8.6. Then find and report, to three places after the decimal, f(0.68).
