Hi Guys,

Been following this thread for sometime now. Ghost reading most times.

Nice work though!

But I'd like to say this, TPG if u wanna start a blog, don't do the normal blogging pple ar used to doing. Create a great level of precision with every topic.

I tink u av d ability to convert succint comment to explanatory verbose ones(I'm guessing u understand things easy). So, I'l stop typing now!

NOTE: there are lotsa blog out there. Urs need to stand out content-wise!

Now, do make "n" the subject of that expression!

Robinhez, lol, was it the comment about eating octopus that made u change ur sign?

Johnny..umm I can't remember now. Nice one!

Keep it up everyone + (me * Ghost readers).

Does this molecule exist?

If YES, what's the IUPAC name?

Where's my pen . . .

Thanks you a lot for "ghostreading" and this addition.

make n the subject of formulae
where A=P(1+R/100)^n



About damn time. - Nick fury. Avengers. cool


Let's do this . . .

A = P( 1+ R/100)^n

Divide both sides by P

A/P = ( 1 + R/100)^n

Take log of both sides.

Log{A/P} = n log {1+ R/100}. Note : [log {A/P} = log A - log P]

Isolate n by dividing both sides by log {1+ R/100}

Then, n = log A - log P/ log (1+ R/100)

I hope I'm right though. grin grin

it looks like it does.
Perhaps it's butyne?

Plzzz, who can integrate x^x dx with respect to x?
The question is answer in video where the problem has been solved with great explanation.

that is the derivative. Which by the way is a little bit easy to solve. He is asking for the antiderivative which does not exist.

I know that it is about the indefinite integral of differentiable function of x which doesn't exist or cannot be solve for in this case. This is the only way to answer the question

It does exist and it's, "tetrahedrane"...

Yes, I know that. That can't be done. You should read my first reply to that question.

I've seen it . . . seems like an unnatural molecule.

How does foirce relate to velocity on an inclined plane?

An object, starting at the top of an inclined plane slides down with a coefficient of friction u.

What is the equation that can calculate its speed upon sliding off at the bottom without knowing it's mass?

V^2(f) - V^1(i)=2as

I saw your app used for math calc, i love it and will like to download one. . any link or name of app?

I've always seen this question, but I've never seen a satisfactory answer. I like the way 'science inclined' peeps here answer questions, and i'm pretty sure this one wouldn’t be exempted.

You saw a shirt worth 97 naira since you don't have cash, you borrowed 50 from your Mom and 50 from your Dad, So you have 100naira since the shirt is 97naira So you have 3 naira left, you returned 1 naira to your Mum and 1 naira to your Dad and you  left 1 naira for urself. Now you owe your Mum 49 naira and your Dad 49naira soo 49+49=98 plus the 1 naira wif u 99 naira WHERE IS THE MISSING NAIRA?

mathlab. Just search for mathlab calculator on Google play.
Thanks for the formula. grin

= 97 naira. wink
You borrowed 100. Returned 2. Kept two. The remaining was used to buy shirt.
Money has finished. No magic. grin

V(i) and V(f) stands for initial and final velocity respectively. .
