The formula used in the calculation is:

$TR = \sin(a) = \frac{O}{H}$

where:

$TR$ is the Trig Ratio
$O$ is the length of first side
$H$ is the length of second side

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:

Length of first side (O): 3 cm
Length of second side (H): 5 cm

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.
