Hi, I am working on MIT 6.189 in hw_2 Ex 2.3
my math functions work in the command line when I use math.sin(math.pi) for example, but when I put the sin and cos values in the multadd function python seems to not recognize the math.sin and math.cos. i tried calling the math library inside the multadd function but it did not work. Does anyone know how to fix this?

What import statment(s) did you use? ``` from math import * ``` Is not that great. You might try: ``` import math ``` They did that poorly in the MIT class.

I did import math .Apparently, I have to be in the command line to write the formula. It does not work in the shell.It is working now. Thanks for your help :)

Strange. I wonder if it has some pathing issue.
