tanθ = y / xUsing pythagoras theroem, x2 + y2 = 1Therefore, cos2θ + sin2θ = 1Lets see an example to understand briefly.Solved Examples on Unit Circle CalculatorExample 1:Find the trigonometric values if the
Sine, cosine and tangent, often shortened to sin, cos, and tan in mathematical operations and on calculator keys, are the most basic trigonometric functions. All three are based on the properties of a triangle with a 90-degree angle, also known as a right triangle. By knowing the sides of...

Unit Circle Reference Angle | Formula, Quadrants & Examples from Chapter 13/ Lesson 10 24K Explore how to find reference angles on a unit circle. Learn about how to use the reference angle formula, and understand the unit circle quadrants and coordinates. ...
Let’s simplify the calculation by assuming we’re on the unit circle (radius 1). Now we can skip the division by 1 and just say sine = height. Every circle is really the unit circle, scaled up or down to a different size. So work out the connections on the unit circle and apply...
