Displaying equations using Tex

One more time on the equations that aren't coming out:

[ tex] v = v_h(v_t/c +1) [/tex]

[ tex] v_t = v_{ht}(v/c +1) [/tex]

[ tex] v = 2c^2v_h / (c^2 + v_h^2)[/tex]

[ tex] v_t = 2c^2v_{ht} / (c^2 + v_{ht}^2)[/tex]

[ tex] v_h = c(c - v_{ht}) / (c +v_{ht}) [/tex]

[ tex] v_ht = c(c - v_h) / (c +v_h) [/tex]

[ tex] v_t = c/Y = DSR(c+v) = v_{ht}(1+ v/c)[/tex]

[ tex] t_{ps} = xv_{ps}= xYv/(1+Y)[/tex]

[ tex] v_{ht} =cDSR[/tex]

v Y [ tex]v_t[/tex] [ tex]v_h[/tex] [ tex]v_{ht}[/tex] DSR

It's ok, everything works now. I put a space in [ tex] to solve it and the other problem was with _{ht} which I tried to write as _h_t which was not accepted. My 1st day using tex so.

x(x_{accel}, \tau) = \frac{-1}{\kappa} + \left(x_{accel} + \frac{1}{\kappa}\right)cosh(\kappa\tau)

Formatted formula should appear below.
$$
x(x_{accel}, \tau) = \frac{-1}{\kappa} + \left(x_{accel} + \frac{1}{\kappa}\right)cosh(\kappa\tau)
$$

If I leave the page and come back it is formatted. But when I just enter the formula and save, the formatting is not there. ?? I can work with that I guess.

This works.

Hi, I have been a member for a considerable period of time but am not allowed to use latex?
 
When you post TeX equations, you might need to refresh the page to see the equations displayed correctly. The dollar signs are used internally by the forum software to indicate regions of a post where the text should be translated as TeX code.

Many thanks
