Because coterminal angles represent integer multiples of 360 or 2, there are an infinite number of coterminal angles with any given angle. WebA: Angle measurements are given,consider =180 Q: 7) Find the missing angle measure, 6, to the nearest hundredth. It is possible for more than one angle to have the same terminal side. {/eq} are {eq}440^{\circ}, -280^{\circ} {/eq} is the only positive coterminal angle within the interval. Any angle has infinitely many coterminal angles because each time we add 360 to that angleor subtract 360 from itthe resulting value has a terminal side in the same location. The thing which can sometimes be confusing is the difference between the reference angle and coterminal angles definitions. First, we recall the coordinate plane where the four quadrants are formed by the intersection of the x and y axes at the origin. Will the tool guarantee me a passing grade on my math quiz? 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.

We start by determining the coterminal angle, which is between 0 and 360 degrees.The quadrant of the coterminal angle is then visible.The reference angle is the same as our specified angle if the terminal side is in the first quadrant (0 to 90). More items Next, we place our initial side in standard position. To find the coterminal angles, simply add or subtract 360 degrees as many times as needed from the reference angle. The thing which can sometimes be confusing is the difference between the reference angle and coterminal angles definitions. Remember that they are not the same thing - the reference angle is the angle between the terminal side of the angle and the x-axis, and it's always in the range of [0, 90] (or [0, /2]). If told to find the least positive angle coterminal So, to check whether the angles and are coterminal, check if they agree with a coterminal angles formula: A useful feature is that in trigonometry functions calculations, any two coterminal angles have exactly the same trigonometric values. At negative 45 degrees the tangent is -1 and as the angle nears negative 90 degrees the tangent becomes an astronomically large negative value. How to tell if two angles are coterminal. {/eq}.
