I am doing the last tasks for "Python week 3" (MOOC). I don't understand the exercise 2.3.
We have to write a function "multadd" that takes 3 params (a, b, c) and return a*b+c. That part is easy, but in the following part of the exercise we have to compute a pair of expressions and we must do it with our "multadd" function. I don't understand how can I do it!

Hi there,

I was also a little puzzled. I just passed 1 to a so it did not change the value of the other two params being added together.

How this helps with your problem.

I rewrote the equations in the form a*b + c
then entered each part of the equation as parameters (a, b, c)  
the first will look like
print multadd(0.5, math.cos(math.pi/4), math.sin(math.pi/4))
I hope it's correct , it gave the same answer as the printed one.
