Need in Matlab Code

Problems 341 Create a function called my_sin, using a midpoint break loop to approximate the value of sin(x),. Determine convergence by comparing successive values of e summation as you add additional terms. These successive sums should be within an absolute value of 0.001 of each other.Test your function by evaluating the my_sin(2) and comparing it to the built-in MATLAB sine function.
