Problem 1 MATLAB A Taylor series is a series expansion of a function f()about a given point a. For one-dimensional real-valued functions, the general formula for a Taylor series is given as ia) (a) (z- a) (z- a)2 + £(a (r- a) + + -a + f(x)(a) (1) A special case of the Taylor series (known as the Maclaurin series) exists when a- 0. The Maclaurin series expansions for four commonly used functions in science and engineering are: sin(x) (-1)"...

2. (New ways to find Taylor series) It's not always easy to write down Taylor series representations by computing all the successive derivatives of a function as follows. (a) Find, by evaluating derivatives at 0, the first three nonzero terms in the Taylor series about 0 for the function g(x) -sin a2 in the text or class such as e", sin , and cos a (b) Use Taylor series expansions already es to find an infinite series representation expansion for...
2. Use the definition of Taylor series to find the Taylor series of f(x)=sin(2x), centered at ca. You need not write your answer in summation notation, but you do need to list at least 4 nonzero terms. 4
An alternative way for calculating sin(x) is to use its Taylor series as the following: sinx)x-+ Create a function named "sin_taylor" in MATLAB. This function takes two inputs. First input is the angle, and the second input determines the number of terms in Taylor series for approximation. Check the fidelity of your function by running sin-taylor( 7) and compare it with the exact value of it. Hint: “factorial" is a built-in function that you can use for calculating factorial of...
