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 trigonometric angle?
just an angle, like any other angle.
Which type of angle has a 133 degree?
An obtuse angle.
What is a 213 degree angle?
An angle of 213 degrees is a reflex angle
What is the angle when the terminal side of an angle in standard position lies along one of the axes?
Quadrantal angle
Is 38 pi divided by 4 radians a quadrantal angle?
9.5
Can you find the reference angle of a quadrantal angle?
Yes. Quadrantal angles have reference angles of either 0 degrees (e.g. 0 degrees and 180 degrees) or 90 degrees (e.g. 90 degrees and 270 degrees).
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
Find value of trigonometric functions of quadrantal angle?
sin 0=13/85
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 quadrantal?
a colorblind disease known by cb
What is formula of quadrantal spherical triangle?
There is no single formula: there are several, depending on what information you have and what you wish to know.
What is quadrantal triangle in spherical trigonometry?
It's an equilateral triangle whose legs are all 90-degree arcs. Here's a quadrantal triangle on the earth: -- Start at the north Pole. -- Draw the first side, down along the north 1/2 of the Prime Meridian to the equator. -- Draw the second side westward along the equator, to 90 degrees west longitude. -- Draw the third side straight north, back up to the north Pole. Each side of the triangle is 90 degrees, each interior angle is also 90 degrees, and the sum of its interior angles is 270 degrees. Pretty weird.
What are the types of geometric angles?
Right angle, obtuse angle, acute angle, supplementary angle, complementary angle, interior angle, exterior angle, adjacent angle
What is the angle between the angle of incidence and the angle of reflection?
the angle of incidence is the initial ray angle and the angle of reflection is the reflected ray angle
