Question

Tell me the ans of e​

Answer 1

The distance from the origin is a.

Explanation:

If the point is located at the coordinate
`(a\cos \alpha, a\sin \alpha)`, then its distance from the origin is given by

`r = √(x^2 + y^2) = √((a\cos \alpha)^2 + (a\sin \alpha)^2)`

`\:\:\:\:=√(a^2(\cos^2\alpha + \sin^2 \alpha))`

`\:\:\:\:= a`
