Do you mean you were having a problem finding the antiderivative of ?
With your second problem, complete the square and use trig substitution.
I was working on some new homework and I'm having a hard time antidifferentiating problems like these:
For this one, I tried multiplying it out and got
and tried to use that to find the integral, but I ran into the problem of having to differentiate
Another problem that I can't do is
for when y is greater than or equal to 1 and less than or equal to 5.
On this problem, I have to find the length of the curve. I know the process, but I can't do it if I can't antidifferentiate that equation.
