Homework Statement
Hey so this is a really trivial question.
f(t) = { 0, 0<= t < pi
{ -sin3t, t>=pi
Just having trouble properly shifting this!
The Attempt at a Solution
f(t) = -upi(t)sin(3t)
= -upi(t)sin[3(t-pi+pi)]
= upi(t)sin[3(t-pi+pi)]
How do I take the +pi out?
I know it should end up as:
upi(t)sin[3(t-pi)]
I just don't really understand how from my last step.
thanks for reading!
