f(x)=sin(2x+π/6)怎么求导

f(x)=sin(2x+π/6)怎么求导 求导f(x) = 4x^3 + sin(x^2) 求导f(x)=sin²x. 已知f(x)=cos^2x/1+sin^2x求f'(π/4)求导 f（x）=sin(x+派/6)+2sin 求导 函数f（x）=sin^2x求导 怎么这个函数求导f(x)=[∣x∣^e(-x)] (x^2+(sin x)^2)^1/5 2*sin（x+π/6）求导. sin(πx/2)求导 f(x)=2xlnx怎么求导, f(x)=sin(2x-3π/4）求导 sin^2(x)求导 f(x)=x^2*e^(-x)求导怎么求? sin^2(x)cos2x,怎么求导 怎么对sin^x求导 sin(1/X)求导sin（1/X）怎么求导, y=f（sin^2x）+f（cos^2x）求导 f(x)=sin^2 x,求此函数第75次求导时x=π/12的值
