There are six trigonometric ratios. Although applicable for any angle, they are usually introduced in the context of a right angled triangle. The full names of the main three ratios are sine, cosine, tangent. The other three ratios are reciprocals, which are cosecant, secant and cotangent, respectively.
Suppose ABC is a triangle which is right angled at B. Thus AC is the hypotenuse.
sin(A) = BC/AC = cos(C)
cos(A) = AB/AC = sin(C)
tan(A) = BC/AB
