Musical instruments produce sound by the vibration of a string on a violin, guitar, or piano, or a column of air in a brass or woodwind instrument. The vibration causes a periodic variation in air pressure that is heard as sound. Periodic vibrations create a pleasing, musical sound, while random vibrations sound like noise.

Solution: We know that the domain and range of trigonometric function tan x is given by, Domain = R - (2n + 1)π/2, Range = (-∞, +∞) Note that the domain is given by the values that x can take, therefore the domains of tan x and 3 tan x are the same. Hence the domain of y = 3 tan x is R ...
