`(sintheta+sectheta)^2+(costheta+c o s e ctheta)^2=(1+cosec thetasec theta)^2`

Prove the following identities: (sintheta+sectheta)^2+(costheta+cos e ctheta)^2=(1+secthetacos e ctheta)^2

Prove the following identities: (sintheta-sectheta)^2+(costheta-cos e ctheta)^2=(1-secthetacos e ctheta)^2

If theta epsilon (0, pi/2) then the value of |((sintheta+cosectheta)^2, (sintheta- cosectheta)^2,1 ),((costheta+sectheta)^2, (costheta-sectheta)^2, 1),((tantheta+cottheta)^2, (tantheta-cottheta)^2, 1)|= (A) sintheta+costhetas+tantheta (B) 1 (C) 0 (D) 4

Simplify (sintheta+sectheta)^(2)+(costheta+cosectheta)^(2) .

(sintheta)/(1+costheta) + (1+costheta)/(sintheta) = 2 cosec theta

(sintheta)/(1+costheta) + (1+costheta)/(sintheta) = 2 cosec theta

Prove the following: (sintheta+cosectheta)^2+(costheta+sectheta)^2=Tan^2theta+cot^2theta+7

Prove the following (sintheta +cosectheta) ^2+(costheta+sectheta) ^2=7+tan^2theta+cot^2theta

The minimum value of (sintheta+c o s e ctheta)^2+(costheta+sectheta)^2=
