For example sound and light waves, day length and temperature variations over the year can be represented as a sine.Ībove: a wave generated using the sine function. The sine function is usually used to model periodic phenomena in physics, biology, social sciences, etc. Other ways involve using the law of sines. For example, if sin(α) is to be computed and the lengths of a and c are available, sin(α) = a / c. If the angle itself is unknown, one way to calculate the sine is to know the measurements of the lengths of the side opposite to it as well as the hypotenuse (side c in the figure). Once you have measured the angle, or looked up the plan or schematic, just input the measurement and press "calculate".

If the angle is known, then simply use our sine calculator which supports input in both degrees and radians. How do I graph sine, cosine, and tangent functions on the TI-83 Plus and TI-84 Plus family of graphing calculators 1) Press the Y key to access the Y. It is useful for finding an angle x when sin(x) is known. The arcsine function is multivalued, e.g. The inverse of the sine is the arcsine function: asin(x) or arcsin(x). The reciprocal of sine is the cosecant: csc(x), sometimes written as cosec(x), which gives the ratio of the length of the hypotenuse to the length of the side opposite to the angle.

Other definitions express sines as infinite series or as differential equations, meaning a sine can be an arbitrary positive or negative value, or a complex number. The sine function can be extended to any real value based on the length of a certain line segment in a unit circle (circle of radius one, centered at the origin (0,0) of a Cartesian coordinate system. You can use this sine calculator to verify this.Ī commonly used law in trigonometry which is trivially derived from the sine definition is the law of sines: Since for a right triangle the longest side is the hypotenuse and it is opposite to the right angle, the sine of a right angle is equal to the ratio of the hypotenuse to itself, thus equal to 1. The function takes negative values for angles larger than 180°. In the illustration below, sin(α) = a/c and sin(β) = b/c.įrom cos(α) = a/c follows that the sine of any angle is always less than or equal to one. Tangent Sine/Cosine, Cotangent 1/Tangent, Secant.
They are Sine, Cosine, Tangent, Cotangent, Secant, Cosecant. 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. We have a total of 6 trigonometric functions.
