We are asked to find coterminal angles of {eq}80^{\circ} WebFinding coterminal angles is as simple as adding or subtracting 360 or 2 to each angle, depending In this case, to find the negative coterminal angle,. lessons in math, English, science, history, and more. To arrive at this result, recall the formula for coterminal angles of 1000: Clearly, to get a coterminal angle between 0 and 360, we need to use negative values of k. For k=-1, we get 640, which is too much. Because coterminal angles represent integer multiples of 360 or 2, there are an infinite number of coterminal angles with any given angle. 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. Negative angles and angles greater than a full revolution are more awkward to work with than those in the range of 0 to 360, or 0 to [latex]2\pi [/latex]. First, let's try to find positive coterminal angles by adding a multiple of {eq}360^{\circ} What this ultimately means is that an angle can be both positive or negative, depending on which direction we rotate: counterclockwise (CCW) or clockwise (CW), and that an angle can be represented in more than one way. We will use the above formula to find the coterminal angles. So the coterminal angles formula, =360k\beta = \alpha \pm 360\degree \times k=360k, will look like this for our negative angle example: The same works for the [0,2)[0,2\pi)[0,2) range, all you need to change is the divisor instead of 360360\degree360, use 22\pi2. {eq}440^{\circ} She fell in love with math when she discovered geometry proofs and that calculus can help her describe the world around her like never before.
