Great Site!!

I am trying to go back and *relearn* calculus, on my own, after being out of school for 15 years! Sigh..

I am asked to find dy/dx|t=0 and dy/dx|t=15

They have given the graph of the curve but not the equation. I have the given points and can find the equations of the tangent lines.. I am having a brain fart on how to proceed.. Do I even need the equation of the curve.?


This is the first word problem on the first section covering the derivitive, and I am already stuck... grrrr

Thanks in advance,

angela
 
Oh um didnt think you actually needed to see the graph. I dont know how to show the graph, but it kinda looks like a graph for the equation type
y=squareroot X

with points (0,0) and (15,0.6)

Without fairly specific information about the graph (not to mention the complete text of and instructions for the exercise), I'm not sure how one could come to any conclusions. Sorry.

thanks GENE

I *knew* I was making this too hard by trying to figure out the equation of the graph. Just had to find another point on the tangent line to find the slope.

Thanks GENE
