Computing exponential function using infinite series. Exponential function exp$($x$)$ can be written as Taylor series expansion as $=$ $=0!=1++22!+...+!+...($a$)(12\%)$ Write a C# method to implement exp$($x$).$ Attach the code. $($Hint: use an error epsilon $=$ say $10-7.$ Stop the calculation when the error is less than epsilon.$)($b$)(2\%)$ Test your code with x $=1,$ x $=3,$ and x $=5.$ Show the result such as myexp$(1)=2\mathrm{.}71828,$ myexp $(3)=20\mathrm{.}085,$ myexp$(5)=148\mathrm{.}41$ etc. Here myexp is your code of exponential function $($c$)(2\%)$ Compare your output with C# math library$$s exp method for x $=1,$ x $=3$ and x $=5.$ Display the difference of myexp$($x$)$ Math.exp$($x$)$ and also $($myexp$($x$)$ Math.exp$($x$))/$ Math.exp$($x$).$ Is the percentage error small? $($d$)(4\%)$ Test this with bigger x such as x $=100.$ Show how many steps it takes to calculate when x is as big as $100$; show the absolute error $|$myexp$($x$)$ Math.exp$($x$)|$ and the relative error $|($myexp$($x$)$ Math.exp$($x$))/$ Math.exp$($x$)|.$ What can you conclude about the absolute error and also relative error?
