Use our sin(x) calculator to find the sine of 21 degrees - sin(21 °) - or the sine of any angle in degrees and in radians. Trigonometric Functions - Chart of Special Angles. x° ...

The sine is a trigonometric function of an angle, usually defined for acute angles within a right-angled triangle as the ratio of the length of the opposite side to the longest side of the triangle. In the illustration below, sin(α) = a/c and sin(β) = b/c. From cos(α) = a/c follows that the sine of any angle is always less than or equal to ...

The value of the sine of 45° can be calculated with the following steps:. Consider a circle with a radius of one. Trace the radius at 45° about the horizontal axis and trace two orthogonal lines departing from its intersection with the circumference. Note that you draw a square with diagonal d = 1.; The horizontal and vertical sides of the squares are, respectively, the cosine and the sine ...

The sine function continues indefinitely and has a period of 2π. The maximum and minimum values occur in each period and are separated by a distance of one period. Thus, the key points on a sine graph are (0, 0), (π/2, 1), (π, 0), (3π/2, −1), and (2π, 0). The graphic below helps to visualize how the sine curve is formed for each angle.
