Some of the above equations were created from the WebEQ Equation Editor, some from the Wizard. The equations which appeared satisfactory when entered directly in the Editor and saved as JPEG were: 2, 3, 5, 6. The others needed work and the images shown here were created in one of two ways:

1. From WebEQ's Editor, using modified MathML. (That is, the equation was entered in the Editor, then saved as MathML. The MathML code was then edited in emacs to fix the problem, opened back up in the Editor, and saved as JPEG)
2. From WebEQ's Wizard, using WebTeX. (That is, the equation was hand-coded into WebTeX, which was then entered in Wizard and saved as JPEG.)

Equation Editor original	Improved version	Issues
		Editor does not recognize the ' (single quote) from the keyboard and doesn't include a prime symbol in its palette.
		Editor includes the uppercase Pi symbol, but not lowercase. Default appearance of differentials.
		Default scaling of integral symbol and parentheses.
		Integral scaling, pi again.

WebTeX versions of all equations

  1. $x^{\prime} + y^2 = z_i^2$   (editor can't handle prime symbol)
  2. $-2\ln{|x-2|} + 3\ln{|x-3|} + C$
  4. $\frac{dr}{dt} = \frac{1}{\pi}$ (editor has only uppercase Pi)
  5. $[-1/\sqrt{3},0] \cup [1/\sqrt{3},+\infty]$
  6. $\frac{\cos{x}}{2\sqrt{\sin{x}}}$ (better fonts for function vs. var.)
  7. $A = \displaystyle{ \int_0^1 \frac{\ln{(x+1)}\sqrt{x^2+2x+2}}{x+1} dx}$ (better for dx)
  8. $\frac{1}{2}\displaystyle{\int_0^{\pi/2} \sin^2{3\theta} d\theta} = \frac{\pi}{12}$ (better for dx)

• MathML for the prime symbol is ′ and making it a superscript improved appearance. Code fragment used:

             <msup>
               <mi>x</mi>
               <mo>′</mo>
             </msup>
         

• MathML for lowercase pi is π (i.e., change MathML from uppercase: Π).
• To force italic font with differentials, use

              <mi>d</mi>
              <mi>r</mi>

  rather than

              <mi>dr</mi>
