Question

How to find the amplitude?
y=1/3sin(6θ−7π/4)−5

Answer 1

\[y=\frac{ 1 }{ 3 } \sin(6θ−\frac{ 7\pi }{ 4 })−5\]

Answer 2

amplitude = 1/3
the number in front of trig function

Answer 3

The -5 at the end doesn't change anything?

Answer 4

that just moves the graph 5 units down

Answer 5

Yeah exactly, wouldn't that change how high the graph is going up then, hence changing the amplitude?

Answer 6

no it will not. standing on a platform does not make you taller, but a sense of what is tall.

Answer 7

amplitude is how high or low the graph is going with respect to its starting point.

Answer 8

Alright, thanks guys!
