Using MATLAB Programming to solve this program

**Step 1: Taylor Series Expansions for Cosine and Sine** Given the following Taylor series expansions for cosine and sine, create a program (using a for loop) to determine tan(x), where x is a value from 0 < x < π/2. \[ \cos x = 1 - \frac{x^2}{2!} + \frac{x^4}{4!} - \cdots = \sum_{k=0}^{n} \frac{(-1)^k x^{2k}}{(2k)!} \] \[ \sin x = x - \frac{x^3}{3!} + \frac{x^5}{5!} - \cdots = \sum_{k=0}^{n} \frac{(-1)^k x^{2k+1}}{(2k+1)!} \] This is a mathematical representation of the cosine and sine functions using their Taylor series. The Taylor series is an infinite sum of terms calculated from the values of the function's derivatives at a single point. **Explanation of the Equations:** 1. **Cosine Series:** - The cosine of x, denoted as cos(x), is approximated by an infinite sum. - Each term in the series is derived from the derivatives of cos(x) at x = 0. - The general term is \(\frac{(-1)^k x^{2k}}{(2k)!}\), where k is the term index. 2. **Sine Series:** - The sine of x, denoted as sin(x), is also represented by an infinite sum. - Similarly, each term is derived from the derivatives of sin(x) at x = 0. - The general term is \(\frac{(-1)^k x^{2k+1}}{(2k+1)!}\), where k is the term index. These series provide a way to compute trigonometric functions for values of x using polynomial approximations, which can be useful in writing programs to calculate these functions numerically.
