I have the matrix
-7-5-7
101110
-7-5-7
I need to find the characteristic equation, and find three eigenvectors and eigenvalues.
Could you please show your working as Im trying to learn :)-Firstly,
(x^lnx) -If you can express x^lnx as the composition of two functions then you can apply the chain rule.
The difficulty is that there is no obvious way to express x^lnx as the composition of two func
Hey, I know this is random, but can somebody explain how to use nCr in Calculus?Im taking an IB test soon, and I kinda forgot how to use it.
Thanks!-Suppose that you have n objects, and you want to ch

show work please-2sin²(x) = 1 - sin(x)
2sin²(x)+ sin(x)- 1 = 0
Let y = sin(x)
Use:
2y² + y - 1 = 0
Factor:
(2y - 1)(y + 1) = 0
y = 1/2
or y = -1

Alone, a large hose can fill a pool in half the time it takes a small hose to fill the pool alone. Together, the two hoses can fill the pool in 5 hours. How long does it take each hose to fill the poo
Im solving a quadratic equation by completing the square. It shows you how to do the problem the only thing is one of the steps goes from √(x-1)^2= √3/2 all under the radical to x-1 = √6 /2 the 2 no l
solve the equation7/x+5=2/x-7/x + 5 = 2/x
Get like terms on the same side of the equation.
7/x - 2/x + 5 = 0
5/x = -5
x = -1
If your question is 7/(x + 5) = 2/x, things get a bit different.

there is 4 problems that i need help with!
1) 9x^9 / 16y^4 divided by 6x^8 / 4y^8
2) 4 / x+5 divided by 8 / x^2 - 25
3) x-5 / x^2 divided by x-10 / x^3
4) -1 / x-1 divided by -1 / x-2-1) (9x^9/16y
Solve, try factoring first...
#1. x^2 +3x + 2 = 4
#2. Also if you feel like answering this one

Find the slope of the tangent line to the given polar curve at the point specified by the value of θ.
r = 6sin(θ)
θ = π/3
I attempted this and got the answers 0 and .36397 but both were incorrect. I
(x,y) --> (r,theta)
r=sqrt(x^2+y^2)
theta = arctan or inverse tan of (y/x)
e.g. (3,4) --> (r,theta)
r=sqrt(3^2+4^2)=sqrt(25)=5
theta=arctan(4/3)=53 degrees
so in polar coords, it is (5,53)-x = r
