Question

eliminate theta if x=a cot theta + b cosec theta, y=a cosec theta +b cosec theta​

Answer 1

Step-by-step explanation:

hlo mate here's your answer

Correct option is

C

xy= ab

We have,

x= a(cscθ+cotθ) ……. (1)

y= b(cscθ−cotθ) …….. (2)

From equation (1) and (2), we get

xy= ab(cscθ+cotθ)(cscθ−cotθ)

xy=

ab (csc

2

θ−cot

2

θ)

xy=

ab [∵csc

2

x−cot

2

x=1]

Hence, this is the answer.
