Question

How do you convert `(−1, 5)` into polar form?

Answer 1

`color(purple)((r, theta) = (sqrt26, 101.31^@)`

Explanation:

`"Conversion from rectangular to polar coordinates "`

`r = sqrt (x^2 + y^2), theta = arctan (y/x)`

`(x,y) = 9-1,5)`

`r = |sqrt(-1^2 + 5^2)| = sqrt26`

`theta = arctan (5/-1) ~~ 101.31^@, " as in II Quadrant"`
