`(sin5theta)/(sintheta)` is equal to

sin(5theta)/sintheta is equal to a.16cos^4theta-12cos^2theta+1, b.16cos^4theta+12cos^2theta+1, c.16cos^4theta-12cos^2theta-1, d.16cos^4theta+12cos^2theta-1

If theta lies in the second quadrant, then sqrt((1-sintheta)/(1+sin theta))+sqrt((1+sin theta)/(1-sin theta)) is equal to :

If x=(cos theta)/(1-sintheta), then (cos theta)/(1+sin theta) is equal to

If -pi lt theta lt -(pi)/(2)," then " |sqrt((1-sin theta)/(1+sintheta))+sqrt((1+sin theta)/(1-sin theta))| is equal to :

If -pi lt theta lt -(pi)/(2)," then " |sqrt((1-sin theta)/(1+sintheta))+sqrt((1+sin theta)/(1-sin theta))| is equal to :

(sin7theta+6sin5theta+17sin3theta+12sintheta)/(sin6theta+5sin4theta+12sin2theta) is equal to

(sin7theta+6sin5theta+17sin3theta+12sintheta)/(sin6theta+5sin4theta+12sin2theta) is equal to
