life sucks, im so lazy to read , I need motivation , I want to be an alien so that i can travel faster than light and dont get consumed by the blackhole , All i really need now is her , to be honest, i need to talk the god of the god of the god its nearly bedtime can anyone help me ?

{ln(n+2)/(n+2)} n=1 ? can someone explain the method of differentiation to find if its increasing or decreasing?

use diff to find if this sequence is inc or dec

{ln(n+2)/(n+2)} n=1 ?? how to do this anyone?

f(x,y) = 6x^2 - 2x^3 + 3y^2 + 6xy

fx = 12x - 6x^2 + 6y

fy = 6y + 6x

fy = 0 ; y = -x

fx = 0 ; 12x - 6x^2 + 6y = 0

now i'm wondering should i divide 6 or - 6 into fx because when i substitute y into x ,it would give the same critical points but the

graph aren't the same x(1-x) & x(x-1) or it does not matter?

one more thing , i'm not so sure on how to tell the the points in

the equation without using a calculator , i mean like x(1-x)

x = 0 , x =1 ?

determine the intervals on which the function is increasing or decreasing,

and determine when relative maxima and minima occur.

f(x) = x^2 / (x-4)

I differentiate it as usual but i'm not sure what to do next

f(x) = Ln(2+x / 2-x)

I need to Initialises the people, and set the name & weight of them as below

here it is : john , 55

alan , 45

joe , 40

alice, 40

kate , 60

public abstract class people {

public String john, alan, joe, alice, kate;

public people(String name, int weight)

{

weight = 55;

weight = 45;

weight = 40;

weight = 40;

weight = 60;

name = john;

name = alan;

name = joe;

name = alice;

name = kate;

}

public String getName()

{

return name; // ????

}

}

public class john extends people {

public john()

{

super(); // cant find symbol - constructor people()!!

weight = 55;

}

so basically , what I'm tring to do is Initialises both super&sub

class but it won't work. And i was trying to make a method that return

the name and another returning the weight but i can't .

I'm quite new to java stuffs so it would be very kind if you

point me to the right direction.

btw. cant change/touch any of method signature.
