• ### On a sinusoidal graph, say the distance between a minimum and the midline is 7pi therefore the period is "28pi". How come it's actually 1/14?

On this problem I'm solving 28pi is the period however the solution explains that 2pi gets divided by 28pi which reduces to 1/14 and is used for b, for the sinusoidal equation. -5cos (1/14t)+7

• ### On a sinusoidal graph, say were considering w (t)=.9cos (365/2pi (t))+8.2 what determines that the graph has minimums and maximums? Waves?

The only bit of intuition I can gather is that .9 is the constant so to speak and that 8.2 is where it fluctuates from. So using the remaining info, if I just multiplied every thing together what constitutes that this isn't just a normal function but instead has peaks and troughs when graphed?
