Use these this rules in finding the derivative. Derivative of a constant, Derivative of a power, Derivative of a constant times a function, Derivative of sums and differences, Derivative of a product, and Derivative of a quotient.

Find the indicated derivative

1. y = 4x^5 – 3x^4 + 2x^3 – x + π, dy/dx
2. y = (3w^2 – 4)(3w^2 + 4), dy/dw
3. y = t^2 – 6t + 9/t^2 – 5t + 6, dy/dt
4. w = (t + 1)(t^2 – 1)/t^2 + 2t + 1, dw/dt
5. y = x^3 – 125/ x^2 + 5x + 25, dy/dx
6. y = (x / x+ 1 + x – 1 /x ), dy/dx
7. x = (t + 1)(t + 2)(t + 3), dx/dt
8. y = (1/x + 1/x^2 + 1/x^3), dy/dx

Hi

The size of my current PC is starting to frustrate me so I am toying with the idea of downgrading size to a shuttle/cub pc.

I currently use a DFI-Lan party Ultra D which has been a superb motherboard, however i dont really use it to its full poitential and am thinking of ditching the amd 3000+ Processor and going for a Dual Core 3800.

I want to find a board that is reliable and represents good value - I understand that overlcoing pcs in shuttle pcs is a no go hence the idea to upgrade to a dual core and keep it at the locked speeds.

If anyone has an info it would be much appreciated.

What would happen to the region of space between two black holes with equal gravitational pull that were facing each other.
i.e. if you could build a space ship that could (in theory) survive and flew it into this region would it be suspended in the middle in a altered(slower) time.
See crude diagram below () is black hole. ~ is gravitational force. # is space ship

Why when you take any number
after that double it by two
and then plus 100
after that divide by two
and then minus back the number that you think
you will get the answer 50.

Explain through this equation.
(A x B + C )/B - A= C/B

the sign "/" means divide.

I know that your position on the Earth, northern or southern hemisphere, decides which way water spins going down a drain..... high pressure areas in weather spin one way, low pressure areas, another.... so.... what gives the galaxies and black holes their direction of spin?.... all the representations of the MilkyWay that I've seen show us spinning like a hurricane or low pressure area....

Decompose v into two vectors (vector 1 and vector 2), where vectors 1 is parallel to w and vector 2 is orthogonal to w.

What does the word orthogonal mean here?

Also, what does the question mean by decompose?

(1) v = -3i + 2j, w = 2i + j

(2) v = 1 - 3j, w = 4i - j

Find the dot product v times w and the angle between v and w.

(1) v = i + j, w = - i + j

(2) v = i + sqrt{3}(j), w = i - j

What exactly is the angle between them anyway?
