How to determine a reference angle
WebMar 26, 2016 · To solve, you need to think about which angles on the unit circle have cosine values that equal 1 when multiplied by 2. Follow these steps: Isolate the trig function on one side. You solve for cos x by dividing both sides by 2: cos x = 1/2. Determine which quadrants your solutions lie in. WebIn trigonometry we use the functions of angles like sin, cos and tan. It turns out that angles that have the same reference angles always have the same trig function values (the sign …
