Question
The amplitude of a wave represented by displacement equation y = 
sin ωt ± 
cos ωt will be :-
sin ωt ± cos ωt will be :-Options
A.
B.
C.
D.
Solution
y = 
sin ωt ± 
cos ωt
multiplying equation by
y =
sin(ωt ± θ)
θ = tan-1
amplitude =
sin ωt ± cos ωtmultiplying equation by
y =
sin(ωt ± θ)θ = tan-1
amplitude =
