O we maths enthusiast, I'm sure some of us are already familiar with some software/applications that can be used in solving problems. I'm familiar with MATLAB only. From the little I've learnt, I must say it'll be nice if we all can learn how to make use of it or any other similar application.

benbuks: integrate √(x^2 - 1) dx ..

Let x = cosh u
Here are some identities that will be needed to solve this problem
cosh u = 0.5(e^u + e^-u)
sinh u = 0.5(e^u - e^-u)
(cosh u)² = 0.25(e^2u + e^-2u + 2) = 0.5(cosh 2u) + 0.5
(sinh u)² = 0.25(e^2u + e^-2u - 2) = 0.5(cosh 2u) - 0.5
(cosh u)² - (sinh u)² = 1
(cosh u)(sinh u) = 0.25(e^2u - e^-2u) = 0.5sinh 2u
Since x = cosh u & (cosh u)² - (sinh u)² = 1,
x² - (sinh u)² = 1
=>sinh u = √(x² - 1)
Also x = cosh u
=> dx = sinh u du
∫√(x² - 1) dx
∫(sinh u)(sinh u) du
∫(sinh u)² du
∫[0.5cosh 2u - 0.5] du
0.25sinh 2u - 0.5u + k
0.5(cosh u)(sinh u) - 0.5u + k
0.5x√(x² - 1) - 0.5arccosh x + k

i revere to u all to d maths general in dis house. i've missed so much here but all is well sha. i will nid to seat down nd review all wat i av missed . i still remain my humble name as rhydex247
soln.

let y=x^x^x.
which implies y=x^(x^x)
recall dat y=x^x
log bth sides we av
lny=lnx^x.... lny=xlnx....
d/dy(lny)=lnx+1
1/y(dy/dx)=(lnx+1)
dy/dx=y(lnx+1) buh y=x^x
dy/dx=x^x(lnx+1).
now dat we knw dy/dx of y=x^x we
can easily get y=x^(x^x)
log both sides we av
lny=lnx^(x^x)
lny=x^xlnx
d/dy(lny)=vdu/dx+udv/dx where
my u=x nd v=x^x.
dy/dx(1/y)=x^x(1)+x(x^x(lnx+1))
dy/dx=y[x^x+x(x^x( lnx+1))]
recall dat y=x^x^x
finally we have
dy/dx=x^x^x[x^x+x(x^x(lnx+1))]

fnks bro...dunno if it's correct tho
help me solve dis too...created a thread for it before someone dircted me here
substitute the square in d pythagoras triple wit x and prove that x=2

Pls kindly help me out with this : This is a Mathematics brain test...A girl went to school and the teacher asked how old are u? She replied I don't know bt I know that I'm half my mother's age. D teacher asked OK how old is ur mother? She said I don't know but I know dat my dad is 5 yrs older thaan my. Mother. D teacher, den how old s ur dad? She said I don't know but I know dat if we add our ages d answer s 100 yrs... Now how old s d girl, her mum, & her dad?

You need the knowledge of chain rule, product rule and the differentiation of logarithm

Let girl age = x
let mum age = y
let dad age = z
first statement
2x = y . . . . . . (1)
second statement
y + 5 = z. . . . . . (2)
third statement.
I didt get it because of your grammar, it is either:
x + y + z = 100 or
x + z = 100. . . . . (3).
Solve 1, 2, and 3 simulteneously.

let the girl's age b x, mother's age be 2x since girl's age is half of her mum's age then her dad's age =2x+5, but the sum of their ages =100 therefore x+2x+(2x+5)=100, 5x+5=100, 5x=100-5, 5x=95, divide both sides by 5, x=19yrs(girl), 2x=38yrs(her mum), 2x+5=43yrs(her dad)

I do not know how it ranks on applied or pure mathematics scale. Sorry.

Jeez, thank you. I would have prefer to go to UI but their academic calender is a little bit slow (considering age thing *employment/marriage/etc), do you think you talk sense into me?

You are welcome. I do not understand your question. What do you mean by "do you think you talk sense into me"?

Ugh, sorry about that, it was a structural grammatical blunder. The (my) question was asking of your opinion considering "my age" in selection of school. In a better sentence, how old is too old to gain ission? (Note: marriage/employment "age"/financial stability/etc). Thank you sir for your quick response.

determine the eigen values of the matrix A, and an eigen vector correspondin to each eigen value. if d=1 what is A

Abeg help with dis
xy+x-y-2=0.......eq(1)
yz-2y+z-3=0.....eq(2)
xz-2x-z=0.......eq(3 ).....find x,y and z

from equation (1)
xy + x - y - 2 = 0
xy + x - y = 2
x(y+1) - y = 2
x(y+1) = 2 + y
x = (2+y) / (y+1)............(4)
from equation (2)
y = (3-z) / (z-2)..............(5)
To solve for x, y and z
step 1: substitute (5) into (4) to get (6).
Step 2: substitute (6) into (3) to get the value of z.
Step 3: substitute the value of z into (5) to get value of y.
Step 4: substitute the value of y into (4) to get the value of x.

I hail all the mathematics authorities in the house! Please I need a prompt response to this bothersome maths question:

there are two possible routes to Lagos to Ijebu Ode. One route is through Lagos/Ibadan expressway which 100km and the other is through Ikorodu and Epe covering a distance of 80km. A motorist going through the express way can travel 10km/hr faster than the one going through Ikorodu and Epe, and arrive Ijebu Ode 5mins earlier as well. what is the timr spent on the journey to Ijebu Ode by the motorist travelling through the expressway?

thank you all in anticipation!
