What is the graph of one cycle of a sine curve with the given characteristics? Using the form y = a sin bθ, what is an equation for the sine curve? amplitude = 4, period =1/4 pi , and a < 0
Answered by Steve


As you know, the function

<i>a sin(kx)</i> has amplitude a and period 2pi/k, so you can use your requirements to produce the function

-4sin(8x)

But you probably figured that out while you were waiting, right?

Answered by bones
hey cleepus, are those correct?
Answered by Tossboy
I just took the periodic Functions and Trig Unit Test Part 1 and relied on cleepus's answers and literally got 7/24 so just google the questions individually, you will prolly get better results.
