Question

What are the period and amplitude of the function y 2sin4?

Answer 1

hello :
note :

y = A sin(Bx + C) + D

amplitude is A period is 2π/B
in this exercice : 2sin(4x)
amplitude is 2 period is 2π/4= π/2

Answer 2

Explanation:

Alright, lets get started.

The given function is :

`y=2sin(4x)`

The standard form of sin function is given as :

`y=asin(bx+c)`

So when we compare our given function with standard one, we have b as 4

The formula of period is :
`(2\pi )/(b)`

Plugging the value of b as 4 in formula of period, we will have

Period =
`(2\pi )/(4)=(\pi )/(2)`

Amplitude is given as a which is 2

So the answer is period
`(\pi )/(2)` and amplitde 2 : Answer

Hope it will help :)
