Hello, Could you please help me with a problem that I saw in my exam? I have tried to solve it but end up getting one solution which is not correct. There happens to be 2 solutions to the problem which appear periodically. The problem has to be algebraically solved without the use of a graphing calculator so I would appreciate if working is given. Equation 1: p(x) = 5000 cos [∏/2 (x-1)] + 6000 Equation 2: p(x) = 15000 cos [∏/2 (x+((∏/2)-1))] + 25000 Thanks in advance.
