speed is also known as the abs value of velocity #coolmath

the second derivative of position is acceleration!

[Claire Longo @claireSTABmath]

usually when there is a trig function as the denominator for a fraction, it's best to use the quotient rule!

I missed class Friday and am having a hard time with this. Can someone help?

[Claire Longo @claireSTABmath]

when drawing a f(x) graph from the derivative, it doesn't matter if it is drawn above or below the deriv just make sure the slope is right!

[Claire Longo @claireSTABmath]

hey @STAB_MATH, i'm really nervous for our derivatives test next week! do you have any helpful tips?? #thanks

[Claire Longo @claireSTABmath]

pay attention to the slope of f(x) when drawing the derivative, but the y coordinate when drawing f(x) from the derivative

[Claire Longo @claireSTABmath]

when writing the derivative based on a graph. If the slope is positive, the y coordinate on the derivative will be too!

[Claire Longo @claireSTABmath]

you write the anti derivative with a capital F! It would be F(x) #mathisfun

[Claire Longo @claireSTABmath]

@StampMitchell @Geebsmath That is important! to get the equation you'll need the derivative for the slope but the original f(x) for y coord.

[Claire Longo @claireSTABmath]

@Geebsmath plug it into the formula f(x+h)- f(x)/ h! that will just be the f(x) part

[Claire Longo @claireSTABmath]

@Prophet8The the derivative is the tangent line of a function and it describes a change in slope (that's just my own personal definition)

[Claire Longo @claireSTABmath]

don't forget the MAGIC equation for solving derivatives!!! f(x+h)-f(x)/ h!!!!

[Claire Longo @claireSTABmath]

@mackmath1 it would be root 3+x PLUS 3 over the same thing. don't multiply out the bottom just the top. Two things on the top will cancel!

[Claire Longo @claireSTABmath]

@Prophet8The You will actually end up having a "bottom heavy" equation, which your HA is 0!!! (y=0)

[Claire Longo @claireSTABmath]

@Prophet8The factor the top!

[Claire Longo @claireSTABmath]

when you accidentally tweet to your real account... whoops #stabmath

[Claire Longo @claireSTABmath]

@nicmath6789 yeah! plug in x2-1 for f and foil out the numerator. the h should cancel with something on the top then just plug in 0!

[Claire Longo @claireSTABmath]

DONT GIVE UP WHEN PLUGGING IN WHAT X APPROACHES IN A LIMIT GETS YOU 0/0! try multiplying by the conjugate, factoring, and simplifying fracs!

[Claire Longo @claireSTABmath]

woah algebra dates back to around 825 bc! #whoknew
