Question

9tan^2-9sec^2 is equal to

Answer 1

Answer:

Sec^2 theta and cosec^2 theta are tan and cot forms then apply Am greater are equal to GM.

Composite of the square function are secant function based on the Item, Value with the second derivative having impact on 2\sec^4x + 4\sec^2x \tan.

When comparing to all the aspects are derived accordingly

9 sec^2x - 9tan^2x = 9 (sec^2x -tan^2x) = 9×1= 9
