- Simplify the polar equation first before converting to rectangular coordinates.
r= 2 ·sec(
θ−π 2)
r·cos(
θ−π 2)
= 2
r·cos(π
2 −θ)
= 2
r·sinθ= 2
y= 2Practice
Plot the following polar coordinates.
1.( 3 ,^56 π)
2.( 2 ,π 2 )
3.( 4 ,−^76 π)
4.(− 2 ,^53 π)
Give two alternate sets of coordinates for each point.
