Question

Find integral

sin 2x · dx
​

Answer 1

To integrate sin2x, also written as ∫sin2x dx, and sin 2x, we usually use a u substitution to build a new integration in terms of u. Let u=2x. We rearrange to get an expression for dx in terms of u. As you can see, we now have a new integration in terms of u, which means the same thing.
