For an angle θ, the functions are calculated this way:Sine Function: sin(θ) = Opposite / Hypotenuse Cosine Function: cos(θ) = Adjacent / Hypotenuse Tangent Function: tan(θ) = Opposite / AdjacentExample: What is the sine of 35°? Using this triangle (lengths are only to one decimal...
Unit Circle Quadrants The unit circle is is a circle with a radius of one and is broken down using two special right triangles. It is useful in mathematics for many reasons, most specifically helping with solving trigonometric functions such as sine, cosine, and tangent. This lesson is going...
