先把tan(4-x^2)^0.5看成一個(gè)整體
對(duì)它的4次求導(dǎo),然后再根據(jù)復(fù)合函數(shù)求導(dǎo)法則,再乘上tan(4-x^2)^0.5對(duì)x的導(dǎo)數(shù)
簡(jiǎn)單來說就是利用復(fù)合函數(shù)求導(dǎo)法則一步一步求導(dǎo)
y'=4(tan(4-x^2)^0.5)^3(1/(cos^2(4-x^2)^0.5))(-1/(4-x^2)^0.5))(-2x)
化簡(jiǎn)自己來

一個(gè)數(shù)學(xué)求導(dǎo)函數(shù)的題,
題是 y=(tan(4-x^2)^0.5)^4
求y'=?希望有清楚步驟.
