Question

Find the period of the function
y=-4 sin t/3

Answer 1

6pi

Answer 2

thanks! how did you get it?

Answer 3

The following general rules apply to the sine and cosine functions:

If y=a sin bx,

then the amplitude of the function is |a| (the absolute value of coefficient ' a '), and the period is \[\frac{ 2\pi }{ b }\]

Answer 4

Look carefully at the given y=-4 sin t/3. What is ' a '? What is ' b '?

Take your ' b ' value and substitute it into 2pi/b to determine the period.

Answer 5

Hint: ' a '=-4. ' b ' = ?

Answer 6

I get 2pi/t/3 right?
