Angle of reference.

The reference angle is the angle that the given angle makes with the x-axis. When the terminal side of the given angle is in the second quadrant (angles from 90° to 180°), our reference angle is calculated by subtracting the given angle from 180 degrees. So, you can use the formula below: Thus, the reference angle of 113° = 180 - 113 = 67°.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. So, if our given angle is 60°, then its reference angle is also 60°.So, you can use this formula. Reference angle° = angle An angle in the first quadrant is its own reference angle. For an angle in the second or third quadrant, the reference angle is \displaystyle |\pi -t| ∣π − t∣ or \displaystyle |180^\circ …The 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. In trigonometry we use the functions of angles like sin, cos and tan. It turns out that angles that have the same reference angles always have the same trig function values (the sign may vary). So for example sin(45) = 0.707. The angle 135° has a reference angle of 45°, so its sin will be the same. Checking on a calculator:
