The point (12,5) is 12 units along, and 5 units up. The domain and range of trigonometric function sine are given by: Domain = All real numbers, i.Usually, the triangles taken for trigonometry calculations are right-angle triangles. In trigonometry, sin, cos, and tan are the basic trigonometric ratios used to study the relationship between the angles and sides of a triangle (especially of a right-angled triangle). When those side-lengths are expressed in terms of the sin and cos values shown in the figure above, this yields the angle sum trigonometric identity for sine: sin(α + β) = sin α cos β + cos α sin β. When the height and base side of the right triangle are known, we can find out the sine, cosine, tangent, secant, cosecant, and cotangent values using trigonometric formulas. The sine, cosine, and tangent ratios in a right triangle can be remembered by representing them as strings of letters, for instance SOH-CAH-TOA in English: . .
