Another LaTeX formatting question

[Borek]

So I was answering in a thread here and what I got was ugly:

$$k_1 = e^{\frac {E_a} {RT_1}}$$

What I don't like is that the exponential part is so small it is barely readable (checked in Opera, Firefox, IE and Chrome). I can write it as

$$k_1 = exp\left({\frac {E_a} {RT_1}}\right)$$

and it definitely looks better, but sometimes I feel like writing e^x instead of exp(x) makes the equation easier to follow - at least for me it is easier to see and group exponents when they are all in superscript position.

Is there a way of making the exponential part larger?

For example OpenOffice formats it as

Still not perfect, but closer to what I am thinking about.

Any ideas?

$$\large k_1 = e^{\frac {E_a} {RT_1}}$$

$$\LARGE k_1 = e^{\frac {E_a} {RT_1}}$$

Increasing the size helps sometimes although it probably isn't too practical.


EDIT:

This here doesn't look too bad $$k_1 = e^{\LARGE\frac {E_a} {RT_1}}$$

$$x^{x}$$
Note how the superscript x is in a smaller font, that dictated by \scriptstyle.

$$a^{a^a}$$
Now note how the font sizes get progressively smaller. The font size goes from that dictated by \displaystyle to \scriptstyle to \scriptscriptsyle (which is where things stop).

$$e^{\frac{E_a}{RT_1}}$$
That "getting progressively smaller" is what is happening here. Both the superscript and \frac act to reduce the font by one level. The end result is that E_a and RT₁ are in that tiny \scriptscriptsyle font.

One way to overcome this is to force the numerator and denominator to be in the size dictated by \scriptstyle:
$$e^{\frac{\scriptstyle E_a}{\scriptstyle RT_1}}$$

Alternatively, just don't use the fractional form:
$$e^{E_a/(RT_1)}$$

With some abuse of notation,
$$e^{E_a/RT_1}$$

Thanks

No idea which one I will use, but it is nice to have some options to select from.

Thank you for bringing this formatting issue to our attention. I understand the importance of clear and easily readable equations. In this case, I would recommend using the math formatting commands in LaTeX to adjust the size of the exponential part. For example, you can use \displaystyle to make the exponent larger and more prominent. Additionally, you can use \textstyle or \scriptstyle to adjust the size of the exponent according to your preference. I also suggest using parentheses or brackets to group the exponent and make it more visually clear. For example, you can write the equation as:

k_1 = e^{\left(\frac {E_a} {RT_1}\right)}

This will make the exponential part more visible and easier to read. I hope this helps and please feel free to reach out if you have any further questions or concerns regarding LaTeX formatting.
