This article explains what a reference angle is, providing a reference angle definition. It will also provide you with a step-by-step guide on how to find a reference angle in radians and degrees, along with a few examples. Keep scrolling, and you'll find a graph with quadrants as well...
If the angle θ is in quadrant IV, then the reference angle θ’ is equal to 360° minus the angle θ. You can use our degrees to radians converter to determine the quadrant for an angle in radians. It’s important to note that reference angles are always positive, regardless if the ...

So, what is a reference angle? A reference angle is the measure of the smallest positive, central angle whose rays are the terminal side and the x-axis. The reference angle on the unit circle can be measured in either degrees or radians....
Tan - Returns the tangent of an angle specified in radians. Text –Converts any value and formats a number or date/time value to a string of text. Time –Returns a date/time value, based on Hour, Minute, and Second values. TimeValue –Converts a time-only string to a date/time valu...
