<p>Calculus is really hard. I'm doing integration right now with 'u' substitution, I'm having problems with inverse trigonometry properties, any help is appreciated.</p>
<p>i think we're doing the same right now... or integration by parts (some w/substitution first). i'll try to help ya if ya pm me.</p>
<p>same ; ill try as well, since that's pretty much where we are too.</p>
<p>i did it a while ago, it comes up quite often tho, i'll answer any questions u want to post</p>
<p>i can help you but what exactly do you need help on? I'm in BC right now, and I remember u substitution pretty well. Be specific about your problem. AIM me if you want help.</p>
