Question

. If x= cot^theta and y= cosec^2theta + 1 then find the value of x- y.​

Answer 1

Answer:

xy=(cosecθ+cotθ)(cosecθ−cotθ)=cosec

2

θ−cot

2

θ

⇒xy=1 (From trignometric laws, cosec

2

θ=1+cot

2

θ)

Answer 2

If x =a cot theta , y =b cosec theta ,then (dy),(dx)= ... If ` cosec theta =x + 1/(4x) ` then the value. play ... If `x = cos theta - cos 2theta, y = sin theta - sin. play.
