Question

Use Pythagorean identities to simplify the given expression. sin^2t+cot^2t sin^2t

Answer 1

sin^4t

Answer 2

1

Answer 3

sory i am wrong

Answer 4

sin(t)^2 + cos(t)^2 * sin(t)^2?
sin(t)^2( 1 + cos(t)^2)
sin(t)^2 ( 2 - sin(t)^2)
2sin(t)^2 - sin(t)^4

Answer 5

cot^2 t = cos^2 t /sin^2 t....cancels the sin^2 t next to it

Answer 6

More identities to be done..

Answer 7

then sin^2 t + cos^2 t = 1

Answer 8

ok thank you

Answer 9

no prob
