Answer 1

find solutions 0,2pie

Answer 2

cos^2t = 1-sin^2t. Substitute and solve the quadratic equation?

Answer 3

\[3sint=2\cos^2t\]

Answer 4

Yes. Replace cos^2t with 1-sin^2t. Then solve for sin(t).

Answer 5

Remember, sin^2t + cos^2t is always equal to 1.

Answer 6

ya a but where did 3 went

Answer 7

I am saying substitute that in the original equation, then solve the fuller thing you get.

Answer 8

ok
