I've been able to solve problems where I'm given 8pi, 7pi/2 or -pi/2, but I can't get the right answer if I'm given -7pi/5 or -9pi/4. I had a video walkthrough for -pi/4, to show me how to do this one. WebHow to find coterminal angles (Step-by-Step)? To find coterminal angles in steps follow the following process: If the given an angle in radians (3.5 radians) then you need to …

WebHe's trying to figure out if 2pi/7 is less than or greater than pi/2. By multiplying the numerator and denominator of pi/2 by 3.5, he gets 3.5pi/7. 3.5 is greater than 2, so 3.5pi/7 (or pi/2) is greater than 2pi/7, which means 2pi/7 would not pass pi/2 which puts it in the first quadrant. WebAug 25, 2024 · A solution is to look for two angles in standard position (angles with the starting side on the positive x-axis) that share the same terminal side. Angles 30 degrees, -330 degrees, and 390 degrees are all coterminal. -86 degrees has a coterminal angle of 274 degrees between 0 and 360 degrees. hornborga.com

WebJun 8, 2024 · 3 What is the Coterminal angle of between 0 and 360? ... What is the Coterminal angle to that is between 0 and 2pi? 6π/7 is coterminal with 48π/7 and lies between 0 and 2π. How do I find the reference angle? So, if our given angle is 110°, then its reference angle is 180° – 110° = 70°. When the terminal side is in the third quadrant ... WebJan 21, 2024 · If you are measuring the angles in degrees, you can add and subtract multiples of 360^o. If you are measuring in radians, add or subtract multiples of 2pi. For example, coterminal to 30^o would be 390^o or -330^o. Coterminal to pi/3 would be pi/3 + (6pi)/3 = (7pi)/3 or pi/3 - (6pi)/3= (-5pi)/3. WebJul 1, 2024 · An angle’s reference angle is the size angle, t, formed by the terminal side of the angle t and the horizontal axis.See Example. Reference angles can be used to find the sine and cosine of the original angle. See Example. Reference angles can also be used to find the coordinates of a point on a circle. hornborgarn ab
