牛顿莱布尼兹公式求由∫（下限为2,上限为y）e^tdt+∫（下限为o,上限为x）costdt=0所确定的隐函数y对x的导

e^(y)-e^(2)+sin(x)=0,y=ln(e^(2)-sin(x)),dy/dx=-cos(x)/(e^(2)-sin(x).
1).(x-1)^4/4|(-1,1)=(1-1))^4/4-(-1-1))^4/4=-4;
2).∫（下限为0,上限为5）|1-x|dx=-∫（下限为0,上限为1）x-1dx+
∫（下限为1,上限为5）x-1dx=-(x-1)^2/2|(0,1)+(x-1)^2/2|(1,5)=17/2;
x√x^2是奇函数,所以∫（下限为-2,上限为2）x√x^2dx=0
