Integration Issues...a bit urgent
Hey having problems with five of my assignment questions, any help would be appreciated.
(problems attached)
For the first one, I tried to solve it by using the sin-1 x as 'u' and integrating the u and getting u3 / 3 + c, but that doesn't seem to work. Then I thought I could use the Integration by parts formula, but since its (sin-1x)2, both u and v would be the same...
Second one: I thought of taking the y0.5 as the substitution 'u', but it doesn't seem to make much difference.
Third one: I thought I could separate it into ln( (1+t)0.5) + ln (t0.5) and solve them individually...
Fourth one: The improper fractions technique, but then I can't seem to get legit values for A, B and C
Last one: Direct Comparison Test, comparing it to the fraction: x2 / (x+3)3
