What is the measure of quadrantal angle?
A quadrantal angle is one whose initial arm is the positive x-axis and whose terminal arm is on the y-axis or the y-axis.In other words, it is k(90 degrees), k is an integer.(in radians: k(pi)/2)
What is the reference angle of negative 200 degrees?
To find the reference angle for negative 200 degrees, first convert it to a positive angle by adding 360 degrees, resulting in 160 degrees. The reference angle is then found by subtracting this angle from 180 degrees, yielding a reference angle of 20 degrees. Thus, the reference angle for negative 200 degrees is 20 degrees.
How do you find the reference angle for a negative angle?
To find the reference angle for a negative angle, first convert the negative angle to its positive equivalent by adding 360 degrees (or (2\pi) radians) until the angle is positive. Once you have the positive angle, determine the reference angle by finding the angle's position in relation to the nearest x-axis (0°, 180°, or 360°). The reference angle is the acute angle formed between the terminal side of the angle and the x-axis. For angles in the second and third quadrants, subtract the angle from 180° or 360°, respectively.
How do you find special angle values using reference radians?
To find special angle values using reference radians, first identify the angle's reference angle, which is its acute angle equivalent in the first quadrant. For example, for an angle of ( \frac{5\pi}{4} ), the reference angle is ( \frac{\pi}{4} ). Then, use the known sine and cosine values of the reference angle, adjusting for the sign based on the quadrant in which the original angle lies. This method allows you to determine the exact trigonometric values for commonly encountered angles like ( \frac{\pi}{6} ), ( \frac{\pi}{4} ), and ( \frac{\pi}{3} ).
What is the reference angle for 243 degree?
The reference angle is the acute angle formed by the terminal side of an angle and the x-axis. For an angle of 243 degrees, which is in the third quadrant, the reference angle can be found by subtracting 180 degrees from it. Thus, the reference angle is 243° - 180° = 63°.

What is a quadrantal angle?
A Quadrantal angle is an angle that is not in Quadrant I. Consider angle 120. You want to find cos(120) . 120 lies in quadrant II. Also, 120=180-60. So, it is enough to find cos(60) and put the proper sign. cos(60)=1/2. Cosine is negative in quadrant II, Therefore, cos(120) = -1/2.

What is a non quadrantal angle?
A quadrantal angle is one that in 0 degrees, 90 degrees, 180 degrees, 270 degrees or 360 degrees (the last one being the same as 0 degrees). These are the angles formed by the coordinate axes with the positive direction of the x-axis. All other angles (in the range 0 to 360 degrees) are non-quadrantal
