What is the integral of #cos2(theta)#? - Socratic
2016年3月13日 · int cos(2theta) "d"theta = 1/2 sin(2theta) + C, where C is an integration constant. I think you mean cos(2theta) instead of cos2(theta). If you know that int cos(x) dx = sin(x) + C, then we can use a substitution (which is the reverse of the chain rule). Let u = 2theta, frac{"d"u}{"d"theta} = 2.
