Post # 30

Well, time has flown by..so fast, i can't believe we're already on week thirty..but anyways, back to actual calculus.

Now, i'm kinda done explaining things I actually understand, so i'm going to halfway explain the things I understand but never finish..so here it goes.

finding a tangent line..

take the derivative of the equation and plug in the x-corrdinates to get your y,
then plug in y to get your slope...

then plug it all into one equation?


definition of a derivative...

take the derivative of the last term at the top..
plug in x for what variable?
or i'm really confused here..


related rates...

find waht the problem is looking for..
list all clues and numbers the problem gives you..
then i forgot how to figure out which equation to use..


These are the major topics that i miss by like one number and always end up getting wrong, i understand integrals now, thanks to alex..so if anyone can help me with these things, i'd appreciate it. I know i didn't say anything i understand, but besides a derivative, I don't have anything..

  1. You're almost there for definition of a derivative!!
    All you do is take the derivative of what is in the parenthesis (first part)

    (Sinh)-(*insert terms here*)
    ----------------------------
    #-h

    Soo...you take the derivative of sinh and plug in what is given for h..0! =]
