surface area = outside are parts.  volume = all what is inside a 3d figure.  they are simular because they both can be found in only 3d figures.  PUSH LIKE :)

Further:  \((-1)^{1/4} \rightarrow e^{i\pi/4}\rightarrow \frac{\sqrt2}{2}(1+i)\)

.

push heart if you think its funny :)

You've not got it quite right!  You need to take the limit as n tends to infinity to get the exponential function:

.

sqrt(i) = (-1)^(1/4)

seriously depends what the question is!...I think yes

Simplify [(1 + x/n)^n]^2 =((n + x)/n)^(2 n)

Simplify (1 - x/n)^n = (-(x - n)/n)^n

you make complex numbers look very easy *dizzy*

3y = 4x+5  | :3

  y =(4/3)x+5/3

\(Consider the functions \[f(x) = \sqrt{\dfrac{x+1}{x-1}}\qquad\qquad\text{and}\\qquad g(x) = \dfrac{\sqrt{x+1}}{\sqrt{x-1}}.\]\)

Explain why f and g are not the same function

that it the way it was meant to be written

x=5 push heart plz :)

the square root of 99 is aproxammetly equal to 9.95 push the heart button plz :)

Whats the point of your first question? couldnt you just call the monstrosity on the right side of the equation 'x'?

and I didnt really get your second question.

the answer is -1...push heart plz :).  You have to use substitution to get the answer...in order to get x you have to replace part of the first formula with the second :)

If a reflection in the line y = -x occurs, then the rule for this reflection is:

a (x, y) in (y, x)

b (x, y) in (-y, -x)

c (x, y) in (x, -y)

d (x, y) in (-x, y)

The rule for this reflection is

b (x, y) in (-y, -x)

Try using the calculator...

They must be the tallest doors in history!!

My pet dinosaur, Red, would be most impressed.  He normally has trouble fitting through doors but with your doors his agrophobia could kick in.  Poor Red he is a bit paranoid.   

Perhaps your question should be reworded a little?

In the figure, ABCD and BEFG are squares, and BCE  is an equilateral triangle.

What is the number of degrees in angle GCE ?

Center of a circle in B with radius r=BG=BE=BC

Central Angle Theorem:

The angle at the centre is twice the angle at the circumference.

\(\beta = \frac{\alpha}{2}=\frac{90^{\circ}}{2}=45^{\circ}\)

Hi Max,

I think you have been watching The Matrix.  :)

Fabulous movie by the way!   (Only the first one)
