The Attempt at a Solution
To be honest, I'm slightly confused as to which path I'm supposed to take with this, especially since I'm not sure what I should be using u to substitute here. This is one of my attempts at solving the question:
∫[(ex-e-x)2 dx]
= ∫[e2x dx] - ∫[e-2x dx]
= (e2x / 2) + (1 / 2e2x) + C
Could someone please tell me if I have the right answer / I'm on the right track / I'm completely wrong? If the latter, I'd appreciate it if you could help get me on track!
Thanks in advance!
