Find reference angle of negative radian
WebReference Angle Calculator To find the reference angle of a negative angle, we have to add 360 or 2 to it as many times as required to find its coterminal angle. For example, to find the reference angle of -1000, we will add 360 three times to it. It implies, - 1000 + 3(360) = -1000 + 1080 = 80. WebA good thing to note before we move on is that when you're on the positive x-axis, the angle is 0° or 360°, which is also known as 2 \pi 2π radians. When you get to the positive y-axis, you'll get 90° or \frac {\pi} {2} 2π radians. The negative x-axis …

WebAngle A is in quadrant II and the reference angle is given by. A r = 180° - 120° = 60°. Example 2: Find the reference to angle A = - 15 π / 4. Solution to example 2: The given angle is not positive and less than 2π. We can use the positive and less than 2π coterminal A c to angle A. A c = - 15 π / 4 + 2 (2 π) = π / 4.
WebA reference angle is the acute version of any angle determined by repeatedly subtracting or adding straight angle (1 / 2 turn, 180°, or π radians), to the results as necessary, until the magnitude of the result is an acute angle, a value between 0 and 1 / 4 turn, 90°, or π / 2 radians.
