1. Find the quadrant of each point and the angle each of the points make with the positive x-axis using the inverse tan function Note: Most calculators will only return values between -90° and 90° (to the right of the y-axis) when using the inverse tan function. An 180° may need to be added if the point is located in the second or third quadrant. (a) (-2,-3) Select the quadrant: O First quadrant O Second quadrant O Third quadrant O Fourth quadrant Angle: (b) (2, -3) Select the quadrant: O First quadrant O Second quadrant O Third quadrant O Fourth quadrant ✓ Measuring clockwise from the positive x-direction: Angle: ✓
