BUT WHERE DOES e COME FROM? ):

Oh wait! I get it.

THATS EXACTLY THE PART I DONT UNDERSTAND! I think I should revise my log and Ln. My teacher said to use Ln instead of log. :/

So how do you end up with x=e^-2

Comprende! Thank you :jump:

So what does the C represent?

Yes! That's where I got up to. The x intercept is when y = 0. I'm just confused about what C is and what it's got to do with anything? Thanks heroic panda (:

Hi, Find y as a function of x, if y' = 1/4x and y= 1 and y = 1 when x = e2. What is the x intercept of this curve? If someone could explain this to me, it would be great. Thank you.

Yes, just y= 1 once (:

Hola! Does anyone know how to do this? Equal volumes of Silver Nitrate Solution and Magnesium chloride solution, each 0.20 mol L-1 are mixed. Determine the concentration of the ions remaining in the resulting solution. Thanks in advance!:sun:

Thank you so much, Kurosaki!:smile: I just don't understand how that shows t varies. If you wouldn't mind could you explain the thought process from this part "Rearrange x to get ..."

Sorry! If i've wasted your time

Oh geez I'm so sorry I should edit my threads before i post them omg Yes that is meant to be 4ay

Oh oops! Yes that's right M is the midpoint of PT

Hi guys does anyone know how to do this? THANKS! The tangent at P(2at,at2) on the parabola x2=4ay meets the x-axis at T Show that as t varies, the locus of M is the parabola 2x2=9xy

thank you omg

So x + py = 2ap + ap^3 Sub in (0,a) 0 +pa = 2ap +ap^3 and then??

What do you mean by RHS and LHS?

Does anyone know how to prove that a normal does not pass through the focus? (if you would like the question just let me know) x
