Question

integrate (e^4t - t^7 + sin(2t))

Answer 1

Hint integrate each term separately.

Answer 2

I get 4e^4t -7t^6 +2cos(2t) +c

Answer 3

Okay, take the derivative of what you got to see if your integration is right.

Answer 4

i was wrong- it is (1/4)e^4t -(1/8)t^8 -(1/2)cos(2t)

Answer 5

Good thing you got it finally. :)
