PrinxArthur1:
Please I need help in this area

Martinez39:
This is not advanced calculus. It's basic.

y² = 2ln x - (2/x) + C

PrinxArthur1:
this is linear equation using separation method

PrinxArthur1:
this is linear equation using separation method

Martinez39:
the equation I wrote is the general solution to the differential equation you gave.

PrinxArthur1:
u just used calculator anybody can do that

Martinez39:
I didn't use calculator, I used the method of separation of variables.

PrinxArthur1:
then show working??

Martinez39:
Lol. Okay, here is my working.

PrinxArthur1:
using which method e.g separation method ?

PrinxArthur1:
Martinez39 thanks a lot......
Can anybody try this one

Martinez79:
y = tan(arctan x + C)

PrinxArthur1:
plsss I need full working abeg...... We get exam tomorrow

Martinez79:
Separating the variables lead to
dy/(1 + y²) = dx/(1 + x²)

Integrating both sides leads to
arctan y = arctan x + C
y = tan(arctan x + C)

PrinxArthur1:
thanks.....alot

PrinxArthur1:
u mean this @ martnez79 and martinez39

Martinez39:

MiseryHimself:
Which school is that?

PrinxArthur1:
Federal polytechnic Nekede Owerri

MiseryHimself:
Makes sense. That's HND?

PrinxArthur1:
yea

MiseryHimself:
Which course?

PrinxArthur1:
is this an interview?
