Plot of the six trigonometric functions, the unit circle, and a line for the angle θ = 0.7 radians. The points labelled 1, Sec(θ), Csc(θ) represent the length of the line segment from the origin to that point.Sin(θ), Tan(θ), and 1 are the heights to the line starting from the x-axis, while Cos(θ), 1, and Cot(θ) are lengths along the x-axis starting from the origin.
Exact Trig Values
Exact Trigonometric Function Values What angles have an exact expression for their sines, cosines and tangents? You might know that cos(60 )=1/2 and sin(60 )=√3/2 as well as tan(45 )=1, but are 30, 45 and 60 the only angles up to 90 with a formula for their trig
Inverse Trigonometric Functions
Understanding and Using the Inverse Sine, Cosine, and Tangent Functions In order to use inverse trigonometric functions, we need to understand that an inverse trigonometric function “undoes” what the original trigonometric function “does,” as is the case with any
(PDF) Trigonometric Identities & Formulas
Right Triangle Definitions of Trigonometric FunctionsNote: sin & cos are complementary angles, so are tan & cot and sec & cos, and the sum of complementary angles is 90 degrees. Adjacent = is the side adjacent to the angle in consideration.

Radicals: Rationalizing the Denominator| Purplemath
To get the “right” answer, I must “rationalize” the denominator. That is, I must find some way to convert the fraction into a form where the denominator has only “rational” (fractional or whole number) values. But what can I do with that radical-three? I can’t take the 3 out, because I don’t have a pair of threes inside the radical.
Sin 60 Degrees
The trigonometry ratios sin, cos and tan for an angle are the primary functions. The value of sin 60 degrees and other trigonometry ratios for all the degrees 0 , 30 , 45 , 90 ,180 are generally used in trigonometry equations. These values are easy to memorize.
