Question

What is the period of `f(t)=sin(3t-pi/4)`?

Answer 1

`(2pi)/3`

Explanation:

The general form of the sine function is : y = asin(bx+c)

where a represents the `color(blue)" amplitude "`

the `color(red)" period " =(2pi)/b`

and c represents the `color(orange)" shift "`

If + c is this denotes a shift to the left of c units
If - c this denotes a shift to the right of c units.

for `sin(3t - pi/4 )color(red)" the period = (2pi)/3`
