Question

Two waves traveling together along the same line are given by

*E**1**=4.00*cos(*π/**4**-ωt)*
and *E**2**=5.00*cos(*π-ωt)* , each
with the same angular frequency. Write the form of the resultant
wave *E*_{R} due to the superposition of the two
waves. You’ll need to find *E*_{R}’s amplitude and
phase angle.
