साबित करें: `(sectheta+costheta)(sectheta-costheta)=tan^2theta+sin^2theta`

costheta-cos2theta=sin3theta

Solve: tantheta+sectheta=2costheta

For any real theta , (csc theta - sin theta)(sectheta-costheta)(tan theta+cot theta)=......

Prove that (sectheta +cosectheta)(sintheta+costheta)=2+secthetacosectheta

(i) (sec theta-cos theta)(cosectheta-"sin"theta)=(1)/("tan"theta+cottheta) (ii) ("sin"theta+sectheta)^(2)+(costheta+cosectheta)^(2)=(1+secthetacosectheta)^(2)

What is the value of (sectheta-costheta)("cosec"theta-sintheta)(cottheta+tantheta) ?

(costheta*csctheta-sintheta*sectheta)/(costheta+sintheta)

If costheta=(4)/(5),sectheta+tantheta=?

Prove that : (sintheta-costheta)/(sintheta+costheta)+(sintheta+costheta)/(sintheta-costheta)=(2)/(2sin^(2)theta-1)

If : (sintheta+csctheta)^(2)+(costheta+sectheta)^(2)=tan^(2)theta+cot^(2)theta+k, then : k =
