Drag the slider to explore changing the value of a in the graph of y = asin (x).

When a = 4, the minimum is - 4

and the maximum is 4

When a = - 4, the minimum is - 4

and the maximum is 4

1a: - 4 & 4

2a: - 4 & 4

Step-by-step explanation:

When a = 4, the minimum is - 4 and the maximum is 4

When a = - 4, the minimum is - 4 and the maximum is 4

(both of them have the same answers)

Answer to the second question: Has no effect on

Te trigonometric function sin (x) has values such:

-1 ≤ sin (x) ≤ 1

Then the minimum value is - 1 and the maximum is 1.

If we have the function:

f (x) = a*sin (x)

We have that the extremal values are when sin (x) is 1 or - 1.

So if a is positive, the maximum value is a and the minimum value is - a

if a is negative, the minimum value is a and th maximum value is - a.
