This article was co-authored by wikiHow staff writer, Krysten Jackson. Coterminal angles can be established by starting on the same side and rotating in a positive or negative direction for more than 360 degrees, finishing on the same side. The resulting coterminal for this equation is -11/6 rad, or -330 if you need to. {/eq} is the only positive coterminal angle within the interval. When calculating the sine, for example, we say: To determine the coterminal angle between 00\degree0 and 360360\degree360, all you need to do is to calculate the modulo in other words, divide your given angle by the 360360\degree360 and check what the remainder is. For those who struggle with math, equations can seem like an impossible task. {/eq} and {eq}-640^{\circ} {/eq}. Lets say your original angle is -17/4 rad. 4 - 4. Find an angle [latex]\beta [/latex] that is coterminal with [latex]\frac{19\pi }{4}[/latex], where [latex]0\le \beta <2\pi [/latex]. add or subtract a multiple of {eq}360^{\circ} If your starting angle is already negative, the last negative coterminal before your cross 0 would be the most negative.

By adding and subtracting a number of revolutions, you can find any positive and negative coterminal angle. You encounter the word angle all the time, not just in your math classes! {/eq}. Everybody needs a calculator at some point, get the ease of calculating anything from the source of calculator-online.net. So if \beta and \alpha are coterminal, then their sines, cosines and tangents are all equal. WebFind the Reference Angle (49pi)/2. Example: Determine Positive and Negative Coterminal Angles. Because coterminal angles represent integer multiples of 360, or 2n, there are an infinite number of coterminal angles with any given angle. {/eq}. 49 2 49 2. Co is the Latin prefix that means two things join or come together and terminal means to end or conclude. Keep reading to learn how to solve this problem. Because we can find coterminal angles by adding or subtracting a full rotation of 360, we can find a positive coterminal angle here by adding 360: We can then show the angle on a circle, as in Figure 19. The "multiple" can be explained like this: In our circular lake scenario, we can walk the path around two or three times. Try refreshing the page, or contact customer support.
