How to describe sine function image
If y = sin (5x + 6 / π), X ∈ R
Change to y = SiNx, X ∈ R
How to change the original image?
If y = sin (5x + π / 6), X ∈ R
Change to y = SiNx, X ∈ R
How to change the original image?
When the abscissa of y = sin (5x + π / 6) is extended to 5 times of the original, we get
y=sin(x+π/6),
If we shift π / 6 units to the right, we will get the following result
y=sinx
