Exact trig values of special angles worksheet answers with work

  • Trigonometry Facts Exact Values of the Trigonometric Functions: Test yourself on the exact values of the six trigonometric functions at the "nice" angles. Click on "Show" and "Hide" in each table cell to control which values are displayed. Work on these values until you know them all!
Exact value means you do not approximate. So if you answer has a radical in it, you leave the radical and do not approximate it. If it has a fraction such as 1/3, you leave it and do not ...

Trigonometric function, In mathematics, one of six functions (sine, cosine, tangent, cotangent, secant, and cosecant) that represent ratios of sides of right triangles.. They are also known as the circular functions, since their values can be defined as ratios of the x and y coordinates (see coordinate system) of points on a circle of radius 1 that correspond to angles in standard positio

    Remark 7 Given a, sin−1 a is the angle θ such that sinθ = a.Thus,sin−1 a is an angle. When you use your calculator to perform this type of operations, you must be aware of whether your calculator is set in degrees or radians; the answer you get will be different, though it will represent the same angle. For example,
