If `sin theta=15/17`, then `cos theta=?`

If sin theta=3/5 , then cos theta =?

If sin theta = 7/25 then find cos theta and tan theta .

If tan theta = 1/b , then ( a sin theta - b cos theta )/( a sin theta + b cos theta) is

Solve sqrt(3) cos theta-3 sin theta =4 sin 2 theta cos 3 theta .

determinant |"cos theta sin theta -sin theta cos theta

Show that ((cos theta - cos 3 theta) (sin 8 theta + sin 2 theta))/((sin 5 theta - sin theta) (cos 4 theta- cos 6 theta))=1

If sin^(3) theta+sin theta cos theta+ cos^(3) theta=1 , then theta is equal to (n in Z)

If A=[{:(cos theta, sin theta),(-sin theta, cos theta):}] then "A A"^(T) is :
