Just a random string of math. How do i make the integration sign bigger,write over a number eg. pi/4 ,input the degree sign and extend the square root sign(if possible)?

More random playing around, I wanted to see how complicated it can get.

To make everything bigger, use \displaystyle in your math tags before writing your code. E.g. \displaystyle \int_a^b{f(x)\,dx} = F(b) - F(a) gives .

To write a fraction, use \frac{}{}, with the numerator in the first set of curly brackets and the denominator in the second. E.g. \frac{\pi}{4} gives .

To input the degree sign, use ^{\circ}, e.g. 30^{\circ} gives .

The square root sign is given by \sqrt{}, write everything you want under it inside the curly brackets. E.g. \sqrt{b^2 - 4ac} gives . - November 6th 2010, 06:09 AMPlato

As a matter of style, I would probably write

\displaystyle \int^{\pi}_{1} \left(\dfrac {\sqrt{\sin (x +60^{3}) + \cos^{2}(x)}} {\csc(3x)}\right)dx

You could end the LaTeX and start on another line with another LaTeX.

However, you can use the table format too.

\begin{array}{rcl}

a(b+c) + b(a + c) &=& ab + ac + ab + bc \\

&=& 2ab + ac + bc

\end{array}

Testing a little.

Nope, the \\ doesn't work outside the array command. - November 6th 2010, 06:57 AMPlato

Hm... never saw this command. Thank you! (Smile)
