Who wanna play a game?

vivie01:
Oh! What do you think we've been saying before about knights? They are dangerous and destructive! If not for the queen's multiple moves, it would have been following the knights at the back.

If your knights are captured early, it will take your expertise to win that game. In my opinion o, they are the baddest!

rationalmind: yes, you can except you got admitted through DE. And it can only be done once

Mr Calculus: plz i need solutions@my generals:
.
(1).if x=Intan(¥/2) and y=tan¥-¥,prove dat d^2y/dx^2=tan^2¥sin¥(cos¥+2sec¥).
(2).if y=[x+root(1+x^2)]^(3/2),
show dat 4(1+x^2)d^2y/dx^2+4xdy/dx-9y=0.
answers will b really appreciated

IVYKORAH: wetin oga

rationalmind: Trust me bro, once clearance starts, you will definitely know. The reason you don't know is because it's yet to start. You might most likely even know before me or tracey.

I hope you're following the thread for newly admitted uniben students. Thats another good place to know when clearance starts

IVYKORAH: thanks ma'am. Lol....whats with d ''hmmnnn''

Elantracey: no not yet

rationalmind: No to the best of my knowledge. I might be wrong o.

OSUU9: Abeg o.u guys shld say smtin about ds online clearance issue b4 i pisz 4 nicka.biko

emasco7: oops...far

Angel235: I shud b d one sayin sowi 4 misquotn....anyway thnks bro

Ghyft: Lagos

Angel235: No i'm still in delta nd kinda confuse. *i'm angel bt not a sis. I'm a guy uh...

Ghyft: THE MILLION DOLLAR QUESTION

Ghyft: the issue is confusing..a friend called me and said that clearance has started all around school and acceptance fee payment has begun......my sister,follow your heart but take your brain along.....i want to tread carefully cos 45K no b beans

Angel235: Guy my frnd hu went 2 Benin just called me nd he is saying he paid his acceptance fee in d skul nd was given acceptance form.......*I just don't get it. mst we go 2 d skul

benbuks: .dude the proof is kinda long oo..guess that‘s why no1 has paste it yet....btw. check. Q1,,‘y=tan¥-¥‘....dont get u ...for d 2nd question i“ll try n post solution later....

Elantracey: y nau

rashywire: pls help with these questions

1. if x and y are real, solve d equation;
jx / 1+jy = 3x+j4/ x+3y



2. if z = a+jb / c+jd , where a,b,c and d are real quantities, show d@
(a) if z is real then a/b = c/d and
(b) if z is entirely imaginary then a/b = -d/c
3. if (R1 + jwL) / R3 = R2 / ( R4 - j 1/wC ) , where R1, R2, R3, R4 , w, L, C are real, show d@
L = ( C R2 R3) / w^2 C^2 R4 ^2 + 1

SOLUTION::
first cross multiply u wud get:
jx^2+j3xy=3x+j4+j3xy+j^24y....
=>>jx^2=3x+j4-4y..
=>>jx^2-3x=j4-4y.
by comparison x^2=4 & 4y=3x.
x=+/-2 and y=+/-3/2
