" 4."tan^(2)A+cot^(2)A+2=sec^(2)A*cosec^(2)A

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

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

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 :

cosec^(2)Acot^(2)A-sec^(2)Atan^(2)A-(cot^(2)A-tan^(2))(sec^(2)Acosec^(2)A-1) =

prove that: tan^(2) phi+cot^(2) phi+2=sec^(2)phi cosec^(2) phi

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

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
