Negative angle reference angle

WebWhen an angle is drawn on the coordinate plane with a vertex at the origin, the reference angle is the angle between the terminal side of the angle and the x x -axis. The … WebLarge and negative angles. Recall that we can apply trig functions to any angle, including large and negative angles. But when we consider the inverse function we run into a problem, because there are an infinite number of angles that have the same tangent. For example 45° and 360+45° would have the same tangent.

WebThe reference angle is always positive. In other words, the reference angle is an angle being sandwiched by the terminal side and the x-axis. It must be less than 90 degree, and always positive. A 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. 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.
