[Tutor] Python Programming Help

[Katie]

Hello,


I am a beginner in computer programming. I am studying math, and the math class that I will be taking requires knowledge in Python. So, I am in a computer science class. Therefore, I do not have an in-depth knowledge of computer programming. 


I am currently trying to write a program in Python version 2.7.5 that uses the math module to compute sinh(x) = 1/2(e^x - e^(-x)) in three ways for a given value of x:
1a) by using the sinh function
1b) by using the exp function
1c) by using the value of e and the exponentiation operator **


2. Print the results and note any differences that appear. 


So, I know that I have to create a NotePad file so that I can import that into my command prompt.


In my NotePad file, I have the following...I'm not sure if I am even going about doing this problem correctly...



def sinh(x):
    return (1/2)*(e^x - e^(-x))
def exp(x):
    return e**x



I am stuck, and don't know where to go from here. I would appreciate help please. 


Thank you.
