Multiplying with makes the equation homogeneous..
Equation is not homogeneous.

You have solved hello, this is a Bernoulli-equation.

Solve this equation for x, (1 + x)^4=34.5 . I am interested in the math libraries you'd use.
the equation is MUCH SIMPLER (1 + x)^4=34.5
thanks

Is there a way to make very long equation multiline so it doesn't stretch the table very long?

Answer Snippets (Read the full thread at stackoverflow):
You can break the equation with the split environment:
\begin{equation} \begin{split} x &= a + b \\ \quad + c + d \\ &= x \cdot y \cdot z \end{split} \end{equation}
Use a p{<length>} type.

I would like to allow the user to enter any equation, like the following, into a text box:
x = x / 2 * 0.07914 x = x^2 / 5
And have that equation applied to telemetry data that is coming from a device connected via a serial port. The incoming data points...

Is that the user entering the equation could enter just about anything which could be a security issue.

Well, it seems simple enough, but I can't find a way to add a caption to an equation. The caption is needed to explain the variables used in the equation, so some kind of table-like structure to keep it all aligned and pretty would be great.

How can I find equation of a line or draw a line, given a starting point, length of line and angle of line (relative to x-axis)?

First thing that still we don't know....
An equation of a line is like; m*x + n = y
m wanna draw a line-segment an you know length, start point and angle, there will be two equation.
To go, you need to be careful how you define your angle .

I have an equation which has been reduced to the form
eqn1 := f(x,y,z) = T;
Now I have another equation that involves T as a variable
eqn2 := g(T,x,y,z);
I want to replace T with f(x) in eqn2 . If I had eqn1 in the form
eqn1better := T = f(x,y,z);
Then...

I need a way of taking an equation given as a string and finding it's mathematical answer, the big caveat is that I can't use eval().
