## cos+4x+sin+4x

sin^4x+cos^4x求导 ： 答:y= (sinx)^4+ (cosx)^4 y'' (x)=4cosx (sinx)^34sinx (cosx)^4 因为: (sinx)^4求导是复合函数求导 sinx=t,则 (sinx)''=cosx (t^4)''=4t^3. sin^4x+cos^4x怎么求导数 ： ^^^原式=分母为其中sin^4x的导数为4sin^3xcosx,而4+cos^4x的导数为4cos^3xsinx. 百度网盟推广. 1. 游戏名. 15.

## How do you prove cos^4(x) sin^4(x) = cos(2x), Socratic

cos4x sin4x = (cos2x +sin2x)(cos2 sin2x) = cos2x sin2x = cosxcosx sinxsinx = cos(x +x) = cos2x
