What is a Trig Ratio?

A Trig Ratio, specifically the sine of angle \(a\), is the ratio of the length of the opposite side to the length of the hypotenuse in a right-angled triangle. It is a fundamental concept in trigonometry used to relate the angles of a triangle to the lengths of its sides.

Example Calculation

Let's assume we have a right-angled triangle with the following sides:

Using the formula:

\[ \sin(a) = \frac{O}{H} = \frac{3}{5} = 0.6 \]

Therefore, the trig ratio (sin(a)) for this example is 0.6.
