Question

Ok i have a graph with an amplitude of A which is 6. And the period is pi. It is a -sin graph. My guess for the equation of this graph was -6sin2x i tried this with parenthises and without no luck. Is there something else it could be or is this simply the wrong equation?

Further description of graph: starts at orgin goes down and like a sin curve goes to -A then back up to A and back to zero. The period of this is pi.

Answer 1

Can you post the actual graph?

Answer 2

Nope i can't pull up the graph
Swear what i say is right i've had two people look at it and screw up too.

Answer 3

So your graph looks like this

Answer 4

Exactly i have no clue how you did that but yup thats it

Answer 5

Thanks fot the help

Answer 6

I used the draw feature

Answer 7

The answer is y = -6*sin(2x), but you can easily do phase shifts to get equivalent answers. However, y = -6*sin(2x) is the most basic one.

Answer 8

So there might be a typo somewhere

Answer 9

could it be that the distance from peak to valley is 6 units? if so, then that would make the amplitude to be 3

Answer 10

Thats what i put in but nothing. If you can think of anything else it would be appreciated but you helped the most for sure

Answer 11

So you also tried y = -3*sin(2x) and that didn't work?

Answer 12

I'll try that too thanks

Answer 13

let me know how it goes

Answer 14

No luck locked out but i had no shot anyway thanks

Answer 15
