∫ydt=∫dt/sint
y=∫sindt/sin^2t=-∫dcost/(1-cos^2t)
=-(1/2)[∫dcost/(1-cost)+∫dcost/(1+cost)]
=-(1/2)ln[(1+cost)/(1-cost)]+c.

基本初等函数的导数:
1.y=c y'=0
2.y=α^μ y'=μα^(μ-1)
3.y=a^x y'=a^x lna
y=e^x y'=e^x
4.y=loga,x y'=loga,e/x
y=lnx y'=1/x
5.y=sinx y'=cosx
6.y=cosx y'=-sinx
7.y=tanx y'=(secx)^2=1/(cosx)^2
8.y=cotx y'=-(cscx)^2=-1/(sinx)^2
9.y=arc sinx y'=1/√(1-x^2)
10.y=arc cosx y'=-1/√(1-x^2)
11.y=arc tanx y'=1/(1+x^2)
12.y=arc cotx y'=-1/(1+x^2)
13.y=sh x y'=ch x
14.y=ch x y'=sh x
15.y=thx y'=1/(chx)^2
16.y=ar shx y'=1/√(1+x^2)
17.y=ar chx y'=1/√(x^2-1)
18.y=ar th y'=1/(1-x^2)
