haven't ..~ no idea before annoymage replied my post~ annoymage : woww..~ never thought of that methods ...~

how did you figure out ? By intuition ? sorry , i think i have some mistake on the earlier question i posted . i forgot to raise the power of x to 2 the f(x) should be f(x) = sqrt( 1 + 1/(x^2) ) sorry about that ..~

does tan u = x work with f(x) = sqrt( 1 + (e^x)/4 ) ?

how am i going to integrate this one? f(x) = sqrt( 1 + 1/x ) sorry for not using the symbol.. because not so familiar with that .. ^.^

sorry ..~ i missed out the negative ..~ now i know already ..~ tq tq ...

how this thing works ? integration of e to the power of (-x) from 0 to infinity sorry , not good in using the symbols ..^.^ ~

I really don't know where to post it..~ due to this question is found in my INTRODUCTION TO THE THEORY OF COMPUTATION ..~ so i assume it is under this section..

o..~ nice explanation ..~ so the nth element is 11111 ..? from 00000 to 11111 ?? can u explain about this line ? You can check that this encodes every subset of C uniquely, and that every combination of c zeroes and ones encodes a subset (even 00...0)... Im not quite sure what it is trying to...

Homework Statement (1)If C is a set with c elements , how many elements are in the power set of C ? explain your answer. (2)If A has a elements and B has b elements , how many elements are in A x B ? explain your answer. Homework Equations The Attempt at a Solution (1)The...

Wow..~ But i deduced tat is Muscle who did kill Sharky..T_T''

i do it like this.. first i negation all of the statements second Then i check it 1 by 1 see whether got contradiction a not(like what u had done) third if there r a contradiction occurs , i will ignore it and go for the next. last i found that it was Muscle...

Sharky , a leader of the underworld , was killed by one of his own band of four henchmen . Detective Sharp interviewed the men and determined that all were lying except for one. He deduced who killed Shark on the basis of the following statements : a) Socko: Lefty Killed Sharky b) Fats...

yup yup~~coz i can't prove this is tvalidity by using truth table..~~

The book which i read for improving my logic sense~ There is a theorem called REPLACEMENT .. ( P \rightarrow Q ) \vee \neg ( P \rightarrow Q) where (P\rightarrow Q) is the second occurrence of ( P \rightarrow Q) But what if the replace the second occurrence with \neg P\vee Q! And i try...

can any1 pls tell me or explain the following..? 1.wat is the meaning of trivial solution? 2.wat is the difference between vector and vector space? 3.wat is vector space...? 4.why is the element in a field is called scalar? 5.how to illustrate a vector space over a field? 6.wat is...
