(sinx/4)^4 求导(sinx/4)^4+(cosx/4)^4 求导
(sinx/4)^4 求导
(sinx/4)^4+(cosx/4)^4 求导
(sinx/4)^4 求导(sinx/4)^4+(cosx/4)^4 求导
答:
[(sinx/4)^4 ]'
=4*[(sinx/4)^3]*[sinx/4]'
=4*[(sinx/4)^3]*(1/4)cos(x/4)
=[(sinx/4)^3]*cos(x/4)
(sinx/4)^4+(cosx/4)^4
=[(sinx/4)^2+(cosx/4)^2]^2-2[(sinx/4)(cosx/4)]^2
=1-(1/2)(sinx/2)^2
=1-(1/2)*(1/2)(1-cosx)
=3/4+(1/4)cosx
求导:
[(sinx/4)^4+(cosx/4)^4]'
=[3/4+(1/4)cosx]'
=-(1/4)sinx
4^sinx求导

求导logx(sinx)!
求导 (1)y=根号2x+sinx (2)y=sinx*Inx (3)y=x/x^2+1 (4)y =In(sinx)
f(x)=sinx/根号(5+4cosx) 的求导..
求导 lim(x->0) x-sinx/x^3+x^4
化简:[1-(sinx)^4-(cosx)^4]/[(sinx)^2-(sinx)^4]
limx趋近0 {【sinx---sin(sinx)】sinx}/(x^4)
limx→0[sinx-sin(sinx)]sinx/x^4
