How to type math equations and symbols on Rhea
To type in math symbols on Rhea, use latex code in between math tags as follows:<math>Insert formula here</math>
To view what to type in for math commands, hit Page| View Source, or Page| Edit. One example: $ f_1(t)=\int_3^t \sin (x) dx $. If you chose "Page, View Source", you would see <math>f_1(t)=\int_3^t \sin (x) dx</math>
Some examples
Some of the most common examples are listed below. To view a comprehensive list, check out some of these off-site links.
Basic text
Suppose that $ f(x) $ is a continuously differentiable function on $ [a,b] $. Let $ N $ be a positive integer and let $ M=\text{Max}\ \{ |f'(x)|: a\le x\le b\} $. Define $ R_N $ to be the the right endpoint Riemann Sum
Sums, integrals, and fractions
$ R_N = \sum_{n=1}^N f(a+n\Delta x)\Delta x $ where $ \Delta x = (b-a)/N $, and let $ I=\int_a^b f(x)\ dx $.
We shall prove that the error, $ E=|R_N-I| $ satisfies the estimate, $ E\le \frac{M(b-a)^2}{N} $.
Trig, dy/dx and triple integrals
$ \frac{1^5}{\sin(\pi)} $
$ \iiint_{F}^{U} x^2+y^3+\sqrt[7]{z}\, d\theta\,dr\,dz $
Matrices
$ \begin{bmatrix} 80 & a & b \\ x_3 & b^3 & \sin(\pi) \end{bmatrix} $
Multi-line Equations
You can align multi-line equations as follows.
$ \begin{align} \bar f(x) &= \oint_S g(x) dx \\ &= \int_a^b g(x) dx \\ &= \frac{\mu_0}{2 \pi a \cdot b} \end{align} $
How to fix tiny type.
Just wanted to point out that a number of one-line functions will render all tiny and ugly unless you go to "My Preferences" at the top of the page, click the "Math" tab, and select "Always render PNG." This will prevent your browser form simply showing you some formatted text instead of rendered, full-size math equations. If
$ y = 4x^2 -3x+1 $
makes you call your eye doctor, then check it out.
