Homework Statement
Basically, I had a test yesterday and one of the questions was:
"an odd function f(x) has a period τ=7. What is the value of f(75)-f(-30)"
Homework Equations
n/a
The Attempt at a Solution
I used periodicity to reduce
= f(75-70) + f(30-28)
= f(5) + f(2)
What else could I have done?
