Chapter 7: Additional Applications of Integration
Section 7.1: Polar Coordinates
Convert the polar point −2,3 to Cartesian coordinates.
According to the note at the end of the Introduction, a negative radius is made positive, but the angle is increased by π.
Write the expression for x.

Write the expression for y.
2 sin3+π = −2⁢sin⁡3→at 5 digits−0.28224
From Example 7.1.3, the polar point 2,3 is in the second quadrant. The polar point −2,3 is a reflection of 2,3 through the origin, and is therefore in the fourth quadrant.
