【解析】 $$ \frac{1}{1+ \tan x} $$ $$ \frac { 1 } { 1 + \tan x } $$ $$ = \frac{\cos x}{\cos x+ \sin x} $$ $$ = \frac{(\cos x+ \sin x)+(\cos x- \sin x)}{\cos x+ \sin x}. \frac{1}{2} \\ = \frac{1}{2}+ \frac{1}{2}\cdot \frac{\cos...
1.指出下列函数的奇偶性,并说明理由。 \$ f ( x ) = \sin x \cos x ; ( 2 ) \int ( x ) = x \cos x\$ (1); \$ f ( x ) = \sin x ^ { 2 } + 1 ; ( 4 ) \int ( x ) = \sin ^ { 2 } x + 2\$ (3). ...
sinwt的导数是wcoswt,不是wsint 因为sinwt是由两种函数即sinx和wt,首先sinx的导数为cosx(x的值为wt),wt的导数为w所以sinwt的导数为这两种导数之积 ,即wcosx,也就是wcoswt这样的题都属于复合函数求导,要先看由几种函数组成,然后再分别求导 相乘 解析看不懂?免费查看同类题视频解析查看解答 更多答案(2) ...
