Question

Consider solution of a differential equation
of a SHM is given by x=a(coswt+sinwt)
which is linear combination of two
solutions. The phase difference between
the two solutions is​

Answer 1

Answer:

x=asin(ωt−α)=acos(ωt−α−

π

)

Another equation is

y=bcos(ωt−α)

∴ The phase difference =(x−y) at t=0

acos(ω.0−α−
