The price of Trigonometry Stock varies sinusoidally with time. At the start of this year, the price of the stock was 110$ per share. Over the next 3 days,

the price climbs to a peak of 120$ per share. If the lowest price the stock reaches is 80$ per share, how much money can you make this year (in 365 days starting from the start of this year) if you begin with 1000$ and time all of your trades perfectly?(Assume you can buy fractions of a share of stock, and that you can buy stock as many times as you want, but can never sell stock you haven't already bought first.)

This is the questions, and I need help finding the function because I don't know the period of this function.

Let the price of stock be represented by equation stock(t)=Asin (kt)+c at t=0 c=110 stock(t)=Asin(kt)+110 at t=3 120=Asin(3k)+110 A=10/sin(3k) the lowest value is 80 c-A=80 110-A=80 A=30 so sin 3k=1/3 k=6.49 degrees/days for 365 days t=365days so we have integrate from 0 to 52.143 weeks and then add 1000 to it stock(t)=30sin(6.49t)+110 now integrate

add 1000+40150.01835254824=41150.01835254824 HOPE THIS HELPS!
