Coterminal and Reference Angles - Expii

Webrotation if the absolute value of the angle is larger than 360o or 2π. If this is the case, you usually will have 2 addition problems or 2 subtraction problems not 1 of each. Determine two coterminal angles, one positive and one negative for each of the angles. Positive Coterminal Negative Coterminal (a) (b) (c) (d) Example) WebFor example, the angles 30°, –330° and 390° are all coterminal (see figure 2.1 below). Fig. 2.1 . In general, if θ is any angle, then θ + n(360) is coterminal angle with θ, for all nonzero integer n. For positive angle θ, the coterminal angle can be found by: θ + 360° Example 2.1: Find three positive angles that are coterminal with ... WebTwo angles are coterminal if the difference between them is a multiple of 360° or 2π. Example: Determine if the following pairs of angles are coterminal. a) 10°, 370°. b) –520°, 200°. c) –600°, –60°. Solution: a) 10° – 370° = –360° = –1 (360°), which is a multiple of 360°. So, 10° and 370° are coterminal. evening with neil gaiman cleveland
