How to find the coterminal angle

Coterminal angles are two angles that are drawn in the standard position (so their initial sides are on the positive x-axis) and have the same terminal side like 110° and -250°

Another way to describe coterminal angles is that they are two angles in the standard position and one angle is a multiple of 360 degrees larger or smaller than the other. That is, if angle A has a measure of M degrees, then angle B is co-terminal if it measures M +/- 360n, where n = 0, 1, 2, 3, ...

45 ° and −315°

90° and 450°

180° and −180°

170° and −190°

100° and −260°

360° and 720°

360° and −360°

Derive using similarity the fact that the length of the arc intercepted by an angle is proportional to the radius, and define the radian measure of the angle as the constant of proportionality; derive the formula for the area of a sector.

What's ?
If you don't know off the top of your head, then you need this section! These critters are going to pop up over and over again in Calculus. The unit circle is a great way to remember your trig values. Remember that it's just a circle with a radius of one... but, it gives us such cool info! If you haven't already, it's time to memorize this thing! Here are the main angles: RADIANS
DEGREES
