A)maximally enhanced? Neglect any reflections from the walls.

Type absolute values of all possible angles in increasing order separating them with commas.

A=??? in degrees

B)cancelled? Neglect any reflections from the walls.

Type absolute values of all possible angles in increasing order separating them with commas.

B=??? in degrees

**bobpursley**, Saturday, December 12, 2009 at 10:25amYou need to find distance from each speaker from the midpoint as a function of the angle.

Then set the difference of distances equal to for a, multiples of wavelength of 277hz, and for b, multiples of half wavelengths.

I would recommend use the law of cosines.

Your known will be the base side (5.5/2 m), theta, and some distance on the radial from midpoint of the speakers to the chosen point, so you know SAS
