Question

Determine which waveform in each of the following pairs is lagging:
a.) cos4t, sin4t;
b.)cos(4t-80), cos (4t)
c.) cos (4t+ 80)
d.) -sin5t, cos(5t+2)
e.) sin 5t+ cos 5t, cos (5t-45)

Can anyone help me with this exercise and also please show me the complete solution so that I can study and understand it well. thank you.
