How to you find the general solution of #dy/dx=3x^3#? Calculus Applications of Definite Integrals Solving Separable Differential Equations 1 Answer Noah G Nov 14, 2016 #y = 3/4x^4+ C# Explanation: #dy = 3x^3dx# #int(dy) = int(3x^3dx)# By the power rule, #int(x^n)dx = x^(n + 1)/(n + 1)# #y = 3/4x^4 + C# Hopefully this helps!
