Cal ~~

Ok~

LEt c wadd i learn in today cal revision

Hmmm~~ intergration normal way

x^x+1/sum of x+1

then if 1/x=ln x

then if e^x=e^x

yeah ....wakkakaak

Hmmm sub method

let take a example

inter 3(x+1)^5 dx

lets c

u=x+1

du=dx

=3(u)^5(du)

=3(u)^5+1/6 du

=1/2(x+1)^6

yeppy ......yahooo~

then if got e^x de then ur u=x ^^

heeheheh ok that wad i learn for now ~~ wkaakakkaak so happy
