Question

SHM is given equation x=[8sin(4xt)+6cos(4xt)cm find amplitude and period
​

Answer 1

Answer:

the eq can be written as

x = A sin ( wt + π/2 )

A = √[ (A1)^2 + (A2)^2 + 2 (A1) (A2) cos π/2 ]

A = √[ (64) + (36)

A = 10

by comparing the eq.

wt = 4xt

w = 4x

2π/ T = 4x

T = 2π/ 4x

T = π/ 2x
