X=a sec theta y= b sin theta . eliminate theta

Answer 1

Hope it's helpful....

Answer 2

Answer:

$(\frac{a}{x})^{2}$ + $(\frac{y}{b})^{2}$ =1

Step-by-step explanation:

x= a secФ

or x= a/cosФ

or cosФ = a/x........(i)

also y= bsinФ

so sinФ= y/b...........(ii)

Now we know that $sin^{2}$Ф + $cos^{2}$Ф = 1

So, using (i) and (ii) we get,

$(\frac{a}{x})^{2}$ + $(\frac{y}{b})^{2}$ =1
