Question 1.
What is the First Shifting Theorem?
Show hintHide hint
Think about how the Laplace transform changes with exponential functions.
Question 2.
If f(t) = cos(t), how would you express L{e^{5t}cos(t)}?
Show hintHide hint
Remember to identify the original function before applying the theorem.
3Question 3.
What does the First Shifting Theorem state?
- L{f(t)} = F(s)
- L{e^{at} f(t)} = F(s-a)
- L{f(t) e^{at}} = F(s+a)
Show hintHide hint
Focus on the relationship between exponential and Laplace transforms.
4Question 4.
