If A/2 is in the first or second quadrants, the formula uses the positive sign. If A/2 is in the third or fourth quadrants, the formula uses the negative sign Cos A2 = ±1+CosA2 If A/2 is in the first or fourth quadrants, the formula uses the positive sign. ...
Sin Double Angle Formula The sine double angle formula is {eq}\sin 2\theta = 2\sin\theta \cos\theta {/eq}. This comes from the angle addition formula. Remember, {eq}\sin (x+y) = \sin x\cos y + \sin y \cos x {/eq}. Then, because {eq}2\theta = \theta + \theta {/eq...
