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.Tangent function ( tan (x) ) The tangent is a trigonometric function, defined as the ratio of the length of the side opposite to the angle to the length of the adjacent side, in a right-angled triangle. It is called "tangent" since it can be represented as a line segment tangent to a circle. In the graph above, tan (α) = a/b and tan (β) = b/a.Finding reference angles (Examples) Terminal side is in the first quadrant. When the terminal side is in the first quadrant (angles from 0° to 90° or from 0 to π/2), the reference angle is the same as the given angle.
