If is in radians, then the formula reads + 2 k. The coterminal angles of 45 are of the form 45 + 360 k, where k is an integer. easiest way to factor cube root. The steps for calculating coterminal angles for angles in radians are the same as those for angles in degrees. Likewise, in radians, we can find coterminal angles by adding or subtracting full rotations of [latex]2\pi [/latex] radians: The angle [latex]\frac{11\pi }{4}[/latex] is coterminal, but not less than [latex]2\pi [/latex], so we subtract another rotation: The angle [latex]\frac{3\pi }{4}[/latex] is coterminal with [latex]\frac{19\pi }{4}[/latex], as shown in Figure 20. For instance, if you need to find a positive and negative coterminal of /4, adding 2 will give you the positive result 9/4 rad and subtracting will give you the negative -7/4 rad. for (var i=0; i \u00a9 2023 wikiHow, Inc.
