Trigonometric ratios are mathematical formulas used to relate the angles and sides of a right-angled triangle. The three main ratios are called sine, cosine, and tangent, also known as sine ratio, cosine ratio, and tangent ratio respectively.
Sine ratio is defined as the ratio of the length of the side opposite the angle to the length of the hypotenuse, cosine ratio is defined as the ratio of the length of the adjacent side to the hypotenuse, and tangent ratio is defined as the ratio of the length of the opposite side to the adjacent side.
In simpler terms, these ratios help us find the length of missing sides of a right-angled triangle given the measure of an angle and the length of one of the sides. These ratios are used in various fields of study, such as physics and engineering, to solve problems related to angles and distances.
Those are 3 of the 6 Trigonometric ratios, the other 3 are Csc or Cosecant, Sec or Secant, and Cot or Cotangent. (but let's not focus on that yet)
Those have formulas;
Which is
Sin(X) = Opposite ÷ Hypotenuse
Cos(X) = Adjacent ÷ Hypotenuse
Tan(X) = Opposite ÷ Adjacent
Whereas X is the reference angle
Those are used to solve the missing sides of the Right triangle using 1 angle and 1 side (depends on where the Reference angle is, whether in the Long leg or short leg, but it cannot be in the right angle)
