if cos(A+B)+sin(A-B)=0and tanB=1/2006.find tanA
if cos (y-z)+cos(z-x)+cos(x-y)=-3/2,prove that cosx+cosy+cosz=0=sinx+siny+sinz
please explain to me hoe to the get this equation of a circle, into standard form. 5x2 -9x + 5y2 -9y -2 = 0
solve with only trig identities, no calc
need to know the answer
no calc just trig identities please show work! thakns so much for any help!
