Question

find two pairs of polar coordinates for points(1,1) satisfying -2pi 12 years ago

Answer 1

i want to find the polar coordinates

Answer 2

the polar coordinates are \((r,\theta)\)

Answer 3

yes i know how to find r and theta but then the condition -2pi<theta<=0 is to be fullfilled to find polar coordinates??

Answer 4

\[r=\sqrt{x^2+y^2}\]
\[\theta = \tan^{-1} \left( \frac {y}{x} \right)\] but theta must be adjusted to fit your criteria, i.e., \(-2\pi<\theta \le 0\)

Answer 5

look at the point. what would theta be regularly? that is, if 0 < theta < pi/2

Answer 6

as (1,1) is in ist coordinaye should we add and subtract 90 to thete
??
