Problem $1$: Solving Nonlinear Equations $($Root Finding Methods$)$

Newton$-$Raphson Method $($MATLAB$)$

Consider the nonlinear equation:

$f(x)=e^x-2sin(x)-3x^2+5=0$

a$.$ Write a MATLAB script to implement the Newton$-$Raphson method function M file to find the root of the equation.

b$.$ Plot the function $f(x)$ and indicate the approximate root you found on the graph.
