Something I found recently that might be interesting for you to solve (cipher codes). The solutions are on the web, so if you want a challenge don't Google the answer. Try and solve them in less than 44 hours without cheating

I will start with the easiest to the hardest:

One hour passed, decoded the first three, lets see if I can get the rest.

Sorry for the double post, but yes, thats my handwriting. Well I took my time to make it as neat as possible

[mGGPrometheus]

Oh it's just a useful trick to deal with integrals of sec^n(x)dx and cosec^n(x) where n is odd. With cosec^n(x) you would multiply the top and bottom by sin(x)

[AxS.pinealan]

Looks like a neat technic that I can use in my exams. Thx Titan!
However, I still wanna know if this is a valid answer. I got this answer after doing integration by part twice.

[mGGPrometheus]

The only sure way to know is take the derivative! It's really close but I think it's

integration by parts is a pretty sweet way to do this problem. It probably requires less work than partial fractons

Quick Comments

AxS.pinealan:

btw, how do you make those images of the answers?

[AxS.pinealan]

Oh right, I forgot the 3 when you integrate that sec^3x. Thx a lot Titan!

Solve for t so that t = -1 + 1/x. Then sub that into the second equation. From there's it should just be a matter of simplifying fractions.

For (a), use the cosine rule

Then in (b), since you know the angle POQ, you can multiple it with the radius to get the arc length. After that i guess you know how to do the perimeter.

As for (c), you need to know the area of the segment PQ. To do that, you first calculate the area of the larger part of sector POQ, which you can do so by multiplying pir^2 with the reflex angle in radians. Then, find out the area of the triangle POQ. That, you can use the sine rule.
Then you just add them up. wala.

I hope that you can understand my messy working

thanks~ ^-^ with this, and some workings i did with the teacher, i think i can solve it~

[mGGNemesis]

stuff here is actually getting pretty serious

[Seffy]

Hey guys,

My friend sent me this picture cos she thought I was good at Mathematics.. clearly I suck LOL so I'm seeing if anyone here have any idea as to what these are, as my friend or myself have no idea what these formulae are. Thanks in advance!

Quick Comments

AxS.pinealan:

lol what are these things, got no idea what they are

[mGGPrometheus]

Top left is Fermat's Last Theorem, which is a famous problem in mathematics that was recently solved by Andrew Wiles.

Top right some kind of Fourier Series in quantum mechanics. In QM you can completely describe objects using different kinds of 'basis states', such a position, momentum, energy, spin etc. In some cases knowledge of one set of states allows you to know another set of states, thanks to the uncertainty principle. I'm not quite sure what it's saying but I think the general gist that one side of the equation is one state (e.g position), the other is another state (e.g momentum), and the equation lets you transform between the two.

Bottom left is an (Inverse) Fourier Transform. If you have a signal whose amplitude varies with time, you can analyze what frequencies it's made up of using a Fourier transform. For example, say you have a piano note being played. The time-signal will be some kind of oscillating wave. Apply a Fourier transform and you can see the different sound frequencies it's made up of. One of the frequencies you see will be the actual note, however you may also see higher frequencies contributing to the timbre of the instrument.

Bottom right is some kind of inner product in quantum mechanics (similar to a dot product except with functions instead of vectors).

Dunno what the middle is
