tan A+cot A=sqrt(sec^(2)A+csc^(2)A)

Prove that : sqrt (sec^(2) A + cosec^(2) A) = tan A + cot A

The expression cosec^(2)A cot^(2)A-sec^(2)A tan^(2)A-(cot^(2)A-tan^(2)A)(sec^(2)A cosec^(2)A-1) is equal to

The expression cosec^(2)A cot^(2)A-sec^(2)A tan^(2)A-(cot^(2)A-tan^(2)A)(sec^(2)A cosec^(2)A-1) is equal to

Prove that : (sin A - cos A) (1 + tan A + cot A) = (sec A)/ (cosec^(2) A) - (cosec A)/ (sec^(2) A)

sqrt(tan^(4) A + cot ^(4) A+ 2)= A) 1 + sec^(2) A + csc^(2)A B) sec^(2)A +csc^(2)A+2 C) sec^(2)A + csc^(2)A - 2 D) 3-sec^(2)A*csc^(2)A

Prove the identity : tan A + cot A = sec A . cosec A

(b) prove that tan^(2)A+cot^(2)A+2=sec^(2)A*cosec^(2)A

(tan A+cot A)=(sec A*csc A)

The value of (tan^2 A+cot^2 A-2)- sec^2 A cosec^2 A is: (tan^2 A+cot^2 A-2)- sec^2 A cosec^2 A का मान क्या होगा ?
