chantalle Posted February 22, 2011 Report Share Posted February 22, 2011 I have such a big problem, I am taking math studies SL, and I am so bad at the derivatives part and the functions and graphs etc. I am so nervous because I don´t get it! I just don´t get it!!!!I trying really hard, but it still not working! Reply Link to post Share on other sites More sharing options...

Rigel Posted March 5, 2011 Report Share Posted March 5, 2011 I could help you. I've been teaching myself derivatives this year, i think i haven't learned too much about derivatives, but i can do my best Reply Link to post Share on other sites More sharing options...
goTiffany Posted June 10, 2011 Report Share Posted June 10, 2011 Are you having trouble finding the derivative?If so then the power rule is the easiest thing to help you :]for example:f(x)= 4x2+5x+4F1(x)= 8x+5First you take 4 times the power, so 4 times 2 = 8. Then you reduce the power of the original variable by one, so you get x1which equals 8x.Next 5 times the power of 1 =5. Then Power of x is reduced by one, which means x is removed completely since it will be x0Since, 4 is a constant and has no x it will be replaced by 0 Reply Link to post Share on other sites More sharing options...
Drake Glau Posted June 10, 2011 Report Share Posted June 10, 2011 For math studies know this:f(x)=xnf'(x)=nxn-1That is it.And recognize the stupid limit function enough to be able to plug stuff into it... Reply Link to post Share on other sites More sharing options...

I give up on tex... Added that to my post, thanks What do you find so hard about tex? Reply Link to post Share on other sites More sharing options...
Drake Glau Posted June 11, 2011 Report Share Posted June 11, 2011 Idk, I never looked at all the coding for it so I was just kinda guessing at it Reply Link to post Share on other sites More sharing options...
Ezeh Posted June 11, 2011 Report Share Posted June 11, 2011 Idk, I never looked at all the coding for it so I was just kinda guessing at it It's pretty easy if you have a read, and it makes the math so much easier to read Reply Link to post Share on other sites More sharing options...
Drake Glau Posted June 11, 2011 Report Share Posted June 11, 2011 Yea, I added it to my little list of links but never read it myself and delta doesnt seem to work? Reply Link to post Share on other sites More sharing options...

To write symbols, you have to prefix the character "\" Also there are capital and lowercase green symbols. So: \delta \Delta Reply Link to post Share on other sites More sharing options...
