Question

Compute f(x)=2t(sin(t^2))dt from -1 to x

Answer 1

t^2 = u
use this :)

Answer 2

ok, thanks :) i was substituting sint^2 by mistake

Answer 3

is it cosx^2-cos1 or cos1-cosx^2?

Answer 4

\[2t*\sin t^2 dt\]
\[t^2= u\]
\[dt = \frac{dy}{2t}\]
\[ \frac{2t}{2t}\sin u*du\]

Answer 5

-cos u
- cos t^2

-cos x^2 + cos 2

Answer 6

sorry cos 1 - cos x^2
