In the diploma thesis, we will learn how to numerically evaluate the sine function and, consequently, also the remaining trigonometric functions. First, we will define trigonometric functions and what identities connect them. Next, we focus on the sine function, as we find that the rest of the functions can be calculated by knowing the sine. For the numerical calculation of the sine function, we first use Taylor's theorem and make sure of its accuracy with an example. Next, we focus on the CORDIC algorithm. We explain how it works and use it to calculate the sine function. Finally, we check what function program languages C and Python use to calculate the sine.
