Derivative of (1/2)e^(x^2) =    • Derivative of (1/2)e^(x^2)  

🚶 𝐒𝐭𝐞𝐩𝐬
00:00 Substitution: u=x^2
00:10 Differentiate in both sides
00:17 Express x in terms of u
00:27 Express dx in terms of u
00:46 Substitute x, x^2 and dx
01:12 Simplify sqrt(u) and take the 2 outside the integral
01:25 Integrate e^u
01:32 Undo substitution: u in terms of x
01:44 Add integration constant +C
01:49 Final answer!
