Submit to Canvas $(3)$ function files. You will need t$$ assign variables and comment appropriately so that

the when you type the help for the functions you get information about the inputs and outputs and your name, course with section, assignment and the due date! If your function does not run with our inputs,we will not debug it and you will lose half of the points on the problem.

Create a no input and no output function called "PiGraphs" which graphs three equations. The

following three equations can be used to approximate Pi$.$ Plot out the value of Pi obtained from these equations on the $y-$axis and the number of values in the sum on the $x-$axis. The figure should calculate the sum out to the first $25$ numbers. Be sure to label your axes and add a title. The figure you create with MATLAB should have a legend with these formatted equations:

a$.1-\frac{1}{3}+\frac{1}{5}-\frac{1}{7}+\frac{1}{9}-...=\frac{}{4}$

b$.\frac{1}{1^2}+\frac{1}{2^2}+\frac{1}{3^2}+\frac{1}{4^2}+...=\frac{{}^2}{6}$

C$.\frac{1}{1^2}+\frac{1}{3^2}+\frac{1}{5^2}+\frac{1}{7^2}+...=\frac{{}^2}{8}$

Consider the diagram in Figure $1$ that describes a simple cable tension problem.

Figure $1$: The length $L_c$ is a cable supporting a hinged beam

The tension, $T$ in Newtons, on the cable is given by: $T=\frac{L_b{L}_{c}W}{D\sqrt[\phantom{2}]{L_c^2-D^2}}$
