Question

Can someone help me with determining the equation for a trig function? I'm aware of how to find the amplitude and period, i'm just confused with this graph!

Answer 1

wait how can we find the amplitute

Answer 2

it's usually the "a", I know how to determine it by looking at an equation

Answer 3

\[\large \text{amplitude} = \frac{|m-n|}{2}\]

m = largest y coordinate of a point on the curve
n = smallest y coordinate of a point on the curve
