### sinx 1 + cosx Example Is sin(2x) 2 = sinxan identity? We have a suspicion this is not an identity. Let’s evaluate both sides at x= 0. sin(2(0)) 2 = 0 2 = 0 sin(0) = 0 Note that this doesn’t prove we have an identity! Try a di erent value of x, since something special might be happening at x= 0. Let’s try x= ˇ=2 sin(2(ˇ=2)) 2 = sin(ˇ) 2
