Question

Cosec€- cot€= 4/5, then cosec€ =
(A) 47/40
B) 59/40
C) 51/40
D)41/40

Answer 1

Step-by-step explanation:

It's very easy

We know that Cot ^2 a - cosec^2 a =1 and using a^2-b^2=(a+b)(a-b)

You know value of cot a - cosec a = -45( equation 1)

Cot a+ cosec a will come (equation 2)

then subtract both equation 1 and 2 you will have your answer .
