**Sine cosine and tangent circle rules by KenHewitt**

There are some special angles that enable us to obtain exact solutions for the functions sin, cos and tan. If we take the two triangles below, and apply the basic trigonometry rules for sine, cosine and... Rules 1) and 2) can be used to prove Rules 3) through 6). The proofs for Rules 4) and 6) are left to the reader in the Exercises for Sections 3.4 and 3.6 (where the Cofunction Identities will be applied).

- (Sine, Cosine and Tangent are often abbreviated to sin, cos and tan 270° etc, and notice that positions can be positive or negative by the rules of Cartesian coordinates, so the sine, cosine and tangent change between positive and negative also. So trigonometry is also about circles! Unit Circle. What you just played with is the Unit Circle. It is a circle with a radius of 1 with its

- are sine, cosine and tangent. They are abbreviated as sin, cosand tanrespectively. Trigonometric ratios are used to find the unknown length or acute angle size in right-angled triangles. It is important to identify and label the features given in a right-angled triangle. The labelling convention of a right-angled triangle is as follows: The longest side of a right-angled triangle is always
