Sin 135 degrees.

We could use the half-angle identity: sin(1/2x)= +- sqrt((1-cosx)/2) 67.5^2 = 1/2(135^@) (Multiply 67.5 xx 2.) The formula doesn't tell us whether sin 67.5^@ is positive or negative, but, since it is an acute angle we know that the sine is positive. (Be careful of the difference between "sign" and "sine"). We also need cos135^@. (That is the special angle that is 45^@ in Quadrant II.) cos135 ...
