Answer 2

@jim_thompson5910 Chose none of these since I did \[\int\limits_{}^{}\frac{ \cos(x) }{ \cos^3(x) }\] equals \[\int\limits_{}^{} \frac{ 1 }{ \cos^2(x)}*\frac{ \cos(x) }{ \cos(x) }\]

Answer 3

Which would be the integral of sec^2 (x)

Answer 4

and what is the integral of sec^2 ?

Answer 5

Wait just noticed that equals tan(x)

Answer 6

yep since

y = tan(x)
dy/dx = sec^2(x)

Answer 7

Got a hundred :)
