Question

if 2y cos theta = x sin theta and 2x sec theta y cosec theta = 3, then the relation between x and y is

Answer 1

2y  cosθ=xsinθ                                     eq 1

2xsecθ-ycosecθ=3                               eq 2 

x=2ycosθ/sinθ

substitute it

2[2ycosθ/sinθ]secθ-ycosecθ=3

4ycosecθ-ycosecθ=3

3ycosecθ=3

ycosecθ=1

y=1/cosecθ

y=sinθ

now substitute the value of sinθ from eq1. 

you will get the answer.
