Question

Categorise the following function of time : sinot + cosot as
(a) Simple harmonic motion
(b) Periodic but not simple harmonic. Also, give the period.​

Answer 1

concept

y = A sinwt

it is a equation of harmonic wave

solution

1 .

y = sinwt + coswt

= √ 2 { sin (wt +π/4)]

so it's a equation of simple harmonic motion

2 .

Time period = 2π/w
