I can't be the only one feeling suspicious about OP and these bunch of new comers commenting and complimenting all of his posts. I wonder how alone one has to be run multiple accounts on an online forum.

Heck! I wasn't talking about the woman. But it's common eveyrday logic that the extra skin there serves for a reason. Oh lawrd! I hate to be the one who has to write this, but yes it does affect the sexual pleasure male gets during masturbation as it is 'rougher' to masturbate.

Taking x as 2 and y as 16 doesn't work either.
Once case generates -105 and the other 0.17

To start with, I'm a HSC failure who failed it and gave up on it because I couldn't stand learning something without knowing all the ins and outs of it. Questions like WHY we are following one method but not other offended me to the point that I started finding sciences dull and boring and left HSC and started learning computer programming. Anyway, after a few years of learning to code, I am jumping into cryptography and complex algorithms and I need to sharpen my maths skills now, and here I am studying everything again from online sources and books and this time I am going to make sure to not be left unsatisfied. Anyway, I was reading an HSC Mathematics books and here's one confusion in Surds and rationalizing their denominators
Consider the following:
(5x-16)/(√y - 10)

Now to solve it the book says you rationalize denominator by removing the surd from the denominator. The book continues by multiplying the above equation with (√y+10)/(√y+10) and in the process having y -100 as denominator. Now all that confuses me is that why not multiply the original statement/equation with
(√y-10) / (√y-10) and remove the surd by applying (a+b)^2 formula? So I tried it out and the two answers differ from each other. Anyway, so here's what i did. Took a value for x and y and used them in both the cases. Now let be elaborate
(* is the multiplication symbol)
Case 1:
(5x-16) / (√y-10)       * (√ y-10)/(√ y-10)

Plotting the values x=10 and y =1000 (I chose y = 1000 for simplicity, you'll know as I solve this)

50-16/100-10       *    100-10/100-10
34*90 / 90 * 90
=3060/8100
=0.377
Now case 2:
(5x-16)/ (√ y-10) * (√ y+10)/(√ y+10)

Plotting 10,1000

50-16/100-10 * 100+10/100+10
34/90   *     110*110
=0.377
Case 1 == Case 2, Proved. Theoretically it should work even after we solve the original
(5x-16) / (√y-10) either by  (√y-10) or (√y+10)

Let's find out
(5x-16) / (√y-10)

Case 1:
(5x-16) / (√y-10)   * (√y-10)/(√y-10)

(5x√y -50x -16√y + 160) / (√y-10)^2 
5x√y -50x-16√y+160 / y+100-20√y    -------equation x

For 10,1000 in equation x
5(10)(100) - 50(10) -10(100)+160/1000+100-20(100)

=3660/'-900

=-4.0666

Case 2 :
(5x-16)/ (√ y-10) * (√ y+10)/(√ y+10)
5x√y +50x -16√y -160 / y-100               ||Difference of square formula in
Plotting 10,1000
5(10)(100) + 50(10)-16(100)-160 /1000-100
5000+500-1600-160/900

=3740/900
=+4.155


Hence case 1 ! = case 2 (is not equal). What the fuck is going wrong here?!




I have not been on in a while but I just want to say im still here. I dont post much because I know I have a lot to learn on my own and there is no reason in asking what I will learn in my cs classes. When I have the know how I will give valuable info to this community but for the next 2 years of my degree ill be here lurking and learning. see ya then.

All that you have to do is make sure you don't end up learning only what is taught to you in your cs classes. Goodluck.

Thanks for the update! I was really worried about you for a sec. See you in two years!

Weren't we all? 

Every language is worth learning (except perl) because it expands your horizons.

To answer directly, yes learn Python, it's one of my top 5 most used languages.

If you don't mind the whitespacing rules and are moderately confident in C++ python will be an easy transition.

I am moderately confident with C++, and whitespacing, I recently read an article about some whitespacing Python rules. Weird, if you ask me. In C++, we don't care about whitespace.

Languages like python will only decrease the use of bad practices. And the biggest pro is that it's a rapid development language, so it is filled with lovely and neat tricks to get things done correctly and fast.

Neat tricks, that is what tempts me to learn Python. I see people doing the same things with python in far less code then it would usually take in C/C++, but I wonder if it gives you the same power

But I don't want to die  The legend said c++ was the ultimate language. I am learning that and PHP already (Fairly aware of the syntax of the two languages, just learning to use them powerfully i.e: getting used to frameworks/libraries and algorithms). Which language should I learn next then? JaVA is not an option, I've done some android development with it before and for some reasons, perhaps a matter of taste, I can't stand that language. There are python, perl and ruby, i know a little python(the syntax to be precise), but I don't go ahead with it because it might make me create bad programming habits because of the lose syntax of the language, and apart from pygame I don't really find a reason to learn it

I can't copy/paste RFC. From programmer stand point you need to know how jpg container is organized.

You're wrong here. QT is a framework which has GUI classes and helpers but you can not use them. QT is brilliant framework and it has many many useful classes which you can use in CLI development.

Would you suggest QT for doing every day and every type of jobs with c++ ? Those include but are not limited to file handling, database management, networking, graphics, working with audios, and xmls and pdfs?
