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?

Best ResponseYou've already chosen the best response.0What 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.

Best ResponseYou've already chosen the best response.0I 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 :)
