Problem $1.$

We have a function that you want to evaluate in MATLAB

$f(x,x)=10x^2-3y^2+5xy-25$

a$)$ Write an anonymous function in MATLAB in a lixescript to ask the user to input $x$ and then to input $y$ and then have the function print out the answer to the screen

b$)$ Have your livescrint plot the value of $f$ vs $x$ from $1$ to $10$ for $y=3.$

c$)$ Use Excel and MatLAB to evaluate the integral of $f(x,y)$ from $1$ to $10$ for $y=3$ using the trapezoidal rule $($or any other numerical method.. including MATLAB built ins$).$ Compare this with the analytical solution. $($I realize I left zu a number of excel sheets and MATLAB files which would work for this with a little modification. You can "pirate" from me but zoud be better off making your own.$)$
