III. Record your answers for the next work and submit them on Moodle by Wednesday, APRIL 7th.

  1. Find the smallest positive A and B so that y=Acos(Bx) with y(0)=10, y(pi/3)=10. 
  2. Find the smallest positive C where y=cos(x + C) with y(-pi/3)=1.
  3. Find an estimate for any and all x  in [-3,3] where  2sin(x) + 3cos(2x) = 1.
  4. Find the smallest positive A, B and C so that y=Acos(Bx +C) has amplitude 3, period 2 and y(-1)=3.
