Question

How to find the sine equation?

Answer 1

I've tried about 20 times. It's based on that info...

Answer 2

No, not like that.

Answer 3

I mean it's 4sin (b+c)

Answer 4

period = 2pi/b
You need a period of pi so what should b =?

Answer 5

2

Answer 6

yes, you already have amplitude down, so we need phase shift

Answer 7

So how do we do that? I thought it was pi/4 but it's not taking that. It won't take pi/8 either

Answer 8

-c/b= phase shift

Answer 9

"Write the equation in the form y = a sin(bx + c) for a > 0, b > 0, and the least positive real number c." if it makes it any clearer
