If x = a cosec θ, y = b cot θ, then the ...

If x = a cosec θ, y = b cot θ, then the value of (x^2/a^2)−(y^2/b^2) = ………………..

A

(1) 1

B

(2) -1

C

(3) tan2 θ

D

(4) cosec2 θ

Text Solution

Verified by Experts

The correct Answer is:
B
`g(x)=1+x-[x]` is grater than 1
since `x[x] gt 0`
`f[g(x)]," since " f(x) =1 " for all " x gt 0`
