Question

If sin a=3/4, prove that whole √cosec^2 A - cot^2 A / sec^2 A -1 =√7/3

Answer 1

If Sin A=¾ (since,sin A=p/h)( perpendicular & hypotenuse)
so,p=3 & h=4
From formula of Pythagoras we know,
H²=P²+B²
B=√H²-P²
B=√4²-3²
B=√7
Put formula in L.H.S. so u can get√7/3
hope it help u........

Answer 2

Step-by-step explanation:

If sin a=3/4,prove that √cosec^A-cot^2A/sec^2 A-1.
