Gifted with this new definition, we can see that angles are pretty powerful things! Learn the basics of co-terminal angles. This works great if you need to find both a positive and a negative coterminal angle. Coterminal angle of 315315\degree315 (7/47\pi / 47/4): 675675\degree675, 10351035\degree1035, 45-45\degree45, 405-405\degree405. To find the coterminal angles to your given angle, you need to add or subtract a multiple of 360 (or 2 if you're working in radians). We can find coterminal angles measured in radians in much the same way as we have found them using degrees. We want to find a coterminal angle with a measure of \theta such that 0<3600\degree \leq \theta < 360\degree0<360, for a given angle equal to: First, divide one number by the other, rounding down (we calculate the floor function): 420/360=1\left\lfloor420\degree/360\degree\right\rfloor = 1420/360=1. {/eq}.

B. For example, notice that 45 degrees and -315 degrees are coterminal angles because they both start and stop at the same place, but just differ in their amount or direction of rotation. Find Positive And Negative Coterminal Angles Example. For example, one revolution for our exemplary is not enough to have both a positive and negative coterminal angle we'll get two positive ones, 10401040\degree1040 and 17601760\degree1760.
