Two coherent sources emit light waves wh...

Two coherent sources emit light waves which superimpose at a point where these can be expressed as
`E_(1) = E_(0) sin(omega t + pi//4)`
`E_(2) = 2E_(0) sin(omega t - pi//4)`
Here, `E_(1) and E_(2)` are the electric field strenghts of the two waves at the given point.
If I is the intensity of wave expressed by field strenght `E_(1)`, find the resultant intensity
