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...

10. The addition of SiO2 can suppress the grain growth of TiO2 crystal, increase the hydroxyl content of TiO2 film, decrease the contact angle for water of TiO2 films and enhance the hydrophilic property of TiO2 films. 在TiO2薄膜中添加 SiO2,可以抑制薄膜中 TiO2晶粒的长大,同时薄膜表面的羟基含量...
Using the cosine formula for addition, we get this ... Notice that the left side of the equation has a sum but the expanded formula on the right side of the equation has a minus sign. The cosine formula is strange in this regard. The left side and the right side of the equation ...
