Here's a cool 0=2 proof I found.
$$a=1, b=2$$
$$2a=b, 2a^2b=ab^2$$
$$2b=b^2, b^2-2b=0$$
$$b(b-2)=0$$

So $$0=2$$...

# Typesetting text in math mode (2)
In a previous post (Typesetting text in math mode) I advertised the use of \mbox to write text in mathematical formulas. This works when you are in the "standard size", but looks funny if you have subscripts because the sizes are off:

#### Can I compile a tcl/tk extended C file into an exe file on windows?
I'm new to tcl/tk. I have a simple tk/tcl extended C file like this,

# Classify a region by its slope
## Definitions
The kth ring of a square matrix of size N, where 1 ≤ k ≤ ceiling(N/2) is the list formed by the elements of the kth and (N-k+1)th rows and columns, but without the first and last k-1 elements.
Example:
Matrix:
1 2 3 4 5
6 7 8 9 1
8 7 6 5 4

# Help With $\int_{-\pi}^\pi{\cos{(y e^{i\cdot 5\cdot t} + z e^{i\cdot 3\cdot t})}dt}$
I have a couple questions that I'd like answered:
(1) How do I evaluate this integral?
(2) Is it possible to do a substitution? What about $u=e^{i \cdot t}$?
(3) What if 5 and 3 are replaced by other constant integers?

# Uniform convergence problem
I encountered this problem while studying for an analysis exam. Here is a related question I asked some days ago.
The problem is as follows: Suppose $a_n$ is a decreasing sequence of positive real numbers and that$$\sum_{n = 0}^{\infty}{a_n \sin{(nx)}}$$ converges uniformly on $\mathbb{R}... | {} |

# Question #93f16
In this case, we have $f \left(x\right) = 4 x + 7$
Thus, for $f \left(x\right) = 0$, we must have $4 x + 7 = 0$
$\implies x = - \frac{7}{4}$ which is the zero of this function. | {} |
