I am not sure how to Integrate this type of problems--
integral squareroot(t^2+t) dt
and integral (5t^2-6)dt
Attempts:
integral sqareroot(t^2+t) dt= 2/3 ((t^2+t) ^(3/2) (2t+1)
And solve the other one same way.
Is that right?
(I am not sure if I differentiate the middle portion when integrating)
you just made it more difficult ...
use ... Wolfram Mathematica Online Integrator to see the antiderivative.
