Find the exact values of sin(u/2) cos(u/2) and tan(u/2) given sin u=24/25 and pie/2 < u < pie

Recall the double/half angle formulas:

We're given , and since is between π/2 and π, we expect to be negative. So from the Pythagorean identity, we find

Also, we know will fall between π/4 and π/2, so both and will be positive. Then we find

and it follows that

it is probably the graph on the bottom right.

answer: c

because if you look at the chart you can see a pattern and compare it to the question he simplify out your

but i think the formula is f(x)=6x
