evaluate integrate 2x ( tan ^1 (4x) ) how do u make integral signs? and how do i make 1 superscript? wat i tried doing here was integration by parts uv  integral vdu that led me in circles i got x^2 tan ^1 (4x )  integral of (x^2)/(1+16x^2) that going in the right direction?

Yes, that looks like a good start. To integrate the last one, Rewrite it as

I reckon I am hardheaded. I type out the code. I tried the MathType, but when the trial ran out I just resorted to doing it by hand.

I used to type in DOS line commands and spend a day setting dip switches in a dotmatrix printer [shudder.] I LOVE GUI and Multitasking! Why not give the suggestions a try? The Lite version of MathType is used in Word and WordPerfect. I use it since I can then use it with the OpenOffice free suite for example, and also send stuff here [I have an extra step to get rid of the surrounding bracketslash and replace with the Latex option given here, but that takes only a second.] As is: \[ \int\limits_{  {\textstyle{\pi \over 2}}}^{{\textstyle{\pi \over 2}}} {\sin ^2 \theta d\theta } \] Changed: From Hermitech Formulator [freeware]: [attachment=0:3nlkxicl]Integral.jpg[/attachment:3nlkxicl] The latter is a JPG image, but can be exported as XML and more. Hermitech is not as friendly as MathType though, and so not as useful.

Thanks. That's right. I forgot Word supports LaTex. I will have to give it a whirl and get used to doing it that way instead of typing of the code.

Just one more quick note: Everything has a learning curve. Some get frustrated at first having to click some icon or dropdown list of icons for each and every step. Like typing, it takes time to become efficient [typing I never learned and never will], but it does become efficient. Also, if using MathType, check preferences/translators to decide which to copy for use in a word processor and which to post here for example.
