Question

What is the polar form of `( 25,16 )`?

Answer 1

`(sqrt881 , 0.57 )`

Explanation:

using the formulae that links Cartesian to Polar coordinates.

`• r^2 = x^2 + y^2`

`• theta = tan^-1(y/x)`

here x = 25 and y = 16

hence `r^2 = 25^2 + 16^2 = 881 rArr r = sqrt881`

and `theta = tan^-1(16/25) = 0.57 "radians"`
