Write a method that returns the 'degree'th Maclauren approximation for e^x evaluated at 'x'. The Maclauren series for e^x is: 1+x+(1/2!)x^2+(1/3!)x^3+...+(1/n!)x . where n is the degree of the Maclauren series. For example, if degree=2 and x=1.2 you would calculate: 1+(1.2)+(1/2!)(1.2)^2 and return that result as a double. If degree=3 and x=2.5 you would calculate: 1+(2.5)+(1/2!)(2.5)^2+(1/3!)(2.5)^3 and return that result as a double.
