Question

For the simple harmonic motion equation d=5sin(pi/4(t)) , what is the maximum displacement from the equilibrium position?

Answer 1

5

The sine part varies from +1 to -1, regardless of its period. So you can ignore what's in the brackets (assuming it's not 0), so the entire function varies from +5 to -5; meaning a maximum of 5 from the equilibrium position.
