There are many methods that can be used to determine the value for sine, such as referencing a table of cosines, using a calculator, and approximating using the Taylor Seriesof sine. In most practical cases, it is not necessary to compute a sine value by hand, and a table, calculator, or some other reference will … See more There are two main ways in which trigonometric functions are typically discussed: in terms of right triangles and in terms of the unit circle. The right-angled triangle definition of trigonometric functions is most … See more Below are a number of properties of the sine function that may be helpful to know when working with trigonometric functions. See more The graph of sine is periodic, meaning that it repeats itself indefinitely and has a domain of -∞<∞. The sine graph has an amplitude of 1; its range is -1≤y≤1.
