Things you need to know about graphing sine and cosine

f(x)= \pm A\sin(Bx)+k and f(x)= \pm A\cos(Bx)+k

1. Identify the midline

2. What is the Amplitude

3. Calculate the Period using the formula P=\frac{2\pi}{B}

4. Divide your Period by four to get four equal distant points

Graph f(x)=-3\sin(\frac{\pi}{5}x)+2
