How to integrate:
Homework Equations
The Attempt at a Solution
I used formula: sin^2(t) = ( 1-cos^2(t))
and now it's:
Then:
u=cos(t)
du=-sin(t)
What to do next?

Not clear, how did you get there: [tex]s=\frac{\sqrt{5}u}{2}[/tex]We may now rewrite the integrand as:
[tex]-6\sqrt{s^{2}+1}, s=\frac{\sqrt{5}u}{2}[/tex]
Now, utilize the trigonometric identity:
[tex]\tan^{2}(y)+1=\frac{1}{\cos^{2}(y)}[/tex]
in a creative way.
