`tan^2A+cot^2A=sec^2A cosec^2A-2`

If 0^@ < A < 90^@ , then the value of tan^2 A + cot^2 A - sec^2 A cosec^2 A is____

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 ?

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

tan^2x + cot^2 x +2=sec^2 x cosec^2 x

If o^(@)ltAlt90^(@) , then the value of tan^(2)A+cot^(2)A-sec^(2)A"cosec"^(2)A is

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

The value of tan^(2)∅+ cot^(2)∅− sec^(2)∅ cosec^(2)∅ is equal to: tan^(2)∅+ cot^(2)∅− sec^(2)∅ cosec^(2)∅ iका मान बराबर है :

tan A + cot A = 2 cosec 2A
