Find the amplitude and period of the graph y=4 sin πθ

The amplitude is 4 and the period is 2

Step-by-step explanation:

In the equation y = A sin (B x)  

∵ The equation is y = 4 sin(πФ)

- Compare it with form above

∴ A = 4 and B = π

∵ A is the amplitude

∴ The amplitude is 4

∵ Period =

∴ Period =

∴ Period = 2

∴ The period is 2

all it means is function 3

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
