Find the period of the function..
y=1.5 cos 6x

ANSWER

EXPLANATION

The given trigonometric cosine function is

This function is of the form,

where B=6.

The period of this cosine function is given by;

We substitute the value of B to obtain;

The correct choice is C

option c

π/3

Given in the question an equation,

y = 1.5sin(6x)

We know that, the period of y = asin(bx) is given by

Period =

here,

a = 1.5

b = 6

so,

plug value in the formula

Period =  2π / (6)

divide by 2

           = 1π / 3

The period of the function is π/3 .
