-2sin6x <<!

anonymous · Answer

if "frequency" is the same as period, then no

anonymous · Answer

the $-2$ is correct

primeralph · Answer

2pi*f = the coefficient of x.
So, it's -2sin(12pi*x)

ranga · Answer

Reflected over the x axis means y should be replaced with -y.  Or simply insert a negative sign before the sin(x).
In f(x) = Asin(Bx), A is the amplitude and frequency = B/2pi

anonymous · Answer

$\frac{2\pi}{b}=6$ gives $b=\frac{\pi}{3}$

ranga · Answer

-2sin(12pi*x)

ranga · Answer

Period = 2(pi)/B  and frequency = 1 /period or B/2pi
