Question

if x =asec theta and y = bcos theta then find xy​

Answer 1

Answer:

I don't understand your questions

Answer 2

Answer:

$x = a \sec( \alpha )$

$y = b \cos( \alpha )$

$xy = (a \sec( \alpha ) )(b \cos( \alpha ) )$

$xy = ab \sec( \alpha ) \cos( \alpha )$

$xy = ab \cos( \alpha ) \frac{1}{ \cos( \alpha ) }$

$xy = ab(1)$

$xy = ab$
