Lol, who can type the solution here? I couldnt type it even with MathJax xD
1/root2 tan (inverse) [root tanx - 1/root tanx]/root2 + 1/2 log |(root tanx - 1)/(root tanx + 1)| + c |

-root2 x c/root tanx - 1 |

alright all mathematicians, lets do a grade 5 problem :D
if a+1/a=4, what is a^2+1/a^2? :D
no calculators required :) |

*no calculators required :)*
What if I need a calculator to solve 4^2 - 2 ?
(which, btw, is the answer ;o) |

*What if I need a calculator to solve 4^2 - 2 ?*
then you wouldnt have solved this problem! xD
i remember getting this as the last problem in my grade 6 or 7's final exam. i was really confused cuz i never saw this idea before (and as usual our teacher never discussed anything even close to this) :D |

*lets do a grade 5 problem :D*

You are carrying nothing. You meet a friend while taking a walk and he gives you 90 candies :D
after that, you take away 43 of them.
How many do you have? |
