Prove that : x²∂²u/∂x² + 2xy ∂²u/∂x∂y + y² ∂²u/∂y²=g(u) [g(u) - 1]
where g(u) = n f(u)/f(u)
By Eulers formula:x ∂u/∂x + y ∂u/∂y = n. f(u)/f(u)
its partial differentian, I need it urgent.-given that x
explain how you would use graphing technology to find the solutions of 0 = −x^2 + 2.5x + 1. What do the solutions of 0 = −x^2 + 2.5x + 1 represent on the graph of the equation?-Im not quite sure what
Whats The 83rd Number In This Pattern5, 10, 15, 20, 25,...?-nth term = a+(n-1)d
= 5+(n-1)*5
83rd term is 5 + 82*5 =
415-This pattern is increasing by plus five, the function would be 5 multiplied by x
The graph of f(x) is given(refer to question 1 of the following website).How would you do the last 3 limits of question 1?The last 3 are:
lim h->0+ [f(h-2)-f(-2)]/h = negative infinity
lim h->0+ [f(
Taking a class and my notes are lost. I cant seem to find everything I need on the internet so maybe someone can help here? Thank you
I need surface area and volume for
A) pentagonal prism
B) hexagon
My problem:
a↓1=2, a↓3=12
as for the people that know what Im talking about or who dont, my arrows mean the number after is shifted down to the bottom (picture it like a exponet on the bottom)
yeahhh
We need a common denominator of 6x, so we multiply 3/2x by 3, and 4/3x by 2. This gives us 9/6x and 8/6x. When we add this up, we end up with:
17/6x-I am not sure abt this bt still:
3/2x +4/3x =(9x +
A car travels 187 miles in 3 hours. How many miles per hour does it travel ?-So remember rate x time = distance.
Rate = distance / time= 187 mi / 3 hrs= 62.3 mi / hr-Technically, the question is ambi
The letters G E O M E T R Y are written on a set of cards. you mix the cards thoroughly. without looking, you draw one letter, replace it, then draw another. Find each probability.
1. P(E,T)
2. P(M,
Solve for x
a)(2+xi)(3-2i) = 12+5i
b) (2+xi)^2 = 4
can anyone show me how to do these examples?-I solved this question on my forum so its easier to read. Feel free to reply back if you have a questi
do I need to rewrite the sin^5(x) in terms of cos? or this integration by parts?
please help.-∫sin^5(x)*cos^8(x) dx from 0 to pi/2
∫sin(x)*sin^4(x)*cos^8(x) dx
Now re-write sin^4(x) in terms of co
Solve (16/y-4)-(4/y)=(16y+4)/(y^2-16) separate answers with a comma.-real solution
y=-5.41125
nonreal(complex)
y=2.20563-2.0014 i
y=2.20563+2.0014 i
you missed a () i think on first y-4( (16/(y-4))-(
so i have to integrate 1/(16+x^2)
=1/(4^2+x^2)
=1/4tan^-1 x/4 +c
is this right? :/ :)-If by 1/4 tan^-1 x/4 +c you mean (1/4)arctan(x/4) + C, then yes. Though its hard to tell whether or not youre doi
Hi, i was wondering if someone could help me with a few math questions
