@jim_thompson5910 Could you help show me how to use sin with this problem?

jim_thompson5910 · Answer

cosine is basically a form of sine, just shifted

hence the name coSINE

jim_thompson5910 · Answer

and all sine functions are sinusoidal

that's where the "sinus" portion comes from (from sine)
