The three basic ratios are sine, cosine and tangent.
In a right angled triangle,
the sine of an angle is the ratio of the lengths of the side opposite the angle and the hypotenuse;
the cosine of an angle is the ratio of the lengths of the side adjacent to the angle and the hypotenuse;
the tangent of an angle is the ratio of the lengths of the side opposite the angle and the the side adjacent to the angle.

Why is calculus important to trigonometry?
In advanced mathematics, familiar trigonometric ratios such as sine, cosine or tan are defined as infinite series. For example, sin(x) = x - x3/3! + x5/5! - ... Such series are used to calculate trig ratios and the proof of their their convergence to a specific value depends on calculus.
