Best ResponseYou've already chosen the best response.02(1cos^2(x/2)) = 2  2cos^2(x/2) doesnt seem to help..

Best ResponseYou've already chosen the best response.0it all depends on what your definition of "simplified" means... are we wanting only single exponents?

Best ResponseYou've already chosen the best response.0one term it already is, but do you mean like sin(x/2) instead of sin^2(x/2)?

Best ResponseYou've already chosen the best response.0hmmmm...... we can play around with identites some and see what happens i spose... do you recall the formula for reducing an exponent?

Best ResponseYou've already chosen the best response.0cos(2a) = cos^2  sin^2 cos(2a)= 1  2sin^2(2a) cos(t) 1  = sin^2(t) 2 try this one

Best ResponseYou've already chosen the best response.0that needs alittle fixing... cos(x)1  = sin^2(x/2) 2 thats what it should be before you put it in
