WebSep 15, 2024 · In general, if two angles differ by an integer multiple of 360 ∘ then each trigonometric function will have equal values at both angles. Angles such as these, which have the same initial and terminal sides, are called coterminal. WebApr 13, 2024 · Today, we'll be covering how to find coterminal angles in both degrees and radians. Be sure to watch every example so you know all the tricks and most effici...

How to Solve Coterminal Angles and Reference Angles?

WebTrigonometry. Find the Reference Angle (19pi)/4. 19π 4 19 π 4. Find an angle that is positive, less than 2π 2 π, and coterminal with 19π 4 19 π 4. Tap for more steps... 3π 4 3 π 4. Since the angle 3π 4 3 π 4 is in the second quadrant, subtract 3π 4 3 π 4 from π π. π− 3π 4 π - 3 π 4. Simplify the result. WebStep 1: Finding co-terminal angle: We find its co-terminal angle by subtracting 2π from it. 8π/3 - 2π = 2π/3 This angle does not lie between 0 and π/2. Hence, it is not the reference angle of the given angle. Step 2: Finding reference angle: Let's check whether 2π/3 is close to π or 2π and by how much. Clearly, 2π/3 is close to π by π - 2π/3 = π/3. 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. citizens home solutions log in
