Sine of x Worksheets

What is the Sine of x Function? In a right triangle, the sine of an angle is the length of the opposite side divided by the length of the hypotenuse. The sine function, along with cosine and tangent, is one of the three most common trigonometric functions. In any right triangle, the sine of an angle x is the length of the opposite side (O) divided by the length of the hypotenuse (H). In a formula, it is written as 'sin' without the 'e': Often remembered as "SOH" - meaning Sine is Opposite over Hypotenuse. For example, you want to find the Sine of an angle C. Based on the given formula we need two lengths: one of opposite side and one of adjacent. Suppose the opposite side AB has length 15 and the adjacent side BC has length 30. We can easily write it like: Sin C = 15 / 30, Sin C = 0.5.
