CBSE Class 12-science Answered
Show that x=Acos(nt+B) + {a/(n2-p2)} satisfies the differential equation d2x/dt2+n2x=asinpt for all
Asked by | 28 Sep, 2008, 10:38: AM
Expert Answer
d2x/dt2 = -n2Acos(nt+B)
d2x/dt2+n2x = -n2Acos(nt+B) + n2 ( Acos(nt+B) + {a/(n2-p2)} ) = n2a / (n2-p2)
which is independent of t. so there is some mistake in this question.
please check it and repost the question.
