Question

Period of y = negative 2 sin x

Answer 1

It has a period of 2pi

the equation to find the period of a sin/cos function is

`period = (2\pi)/(b)`

y = -2 sin(x) has a normal period of 2pi because the b value in this equation isn't stated, making it equal to 1

the basic equation for a sin function is

`y = a \: \sin(b(x - c) ) + d`
