IDK, but I find it much easier writing an equation in point slope form.
The question was write a standard form equation for a line who's slope is 2 and that passes through the point (3,1)

So my answer in point-slope form is
y=2x-5

I heard someone say there's way to convert the point slope form to a standard form, but I'm not sure if this is possible. Please explain how to write it into standard form =]

the particle has the given acceleration, initial velocity and position:
a(t)= 16i+48tj+84t^2k
v(0)=i
r(0)=j-k

A. Find the velocity vector
B. Find the position vector

ok i know that a(t)=v'(t) and v(t)=r'(t)
i thought i could just take the antideriv of a(t) and then v(t) but i didn't get the right answer.

I know that the derivative of a function represents the slope of the function at specific points. So I suppose I was wondering what, if any, information can be gained about the original function by looking at the second (or greater) derivative. Or, if the second derivative doesn't provide any insights into the original function, does knowing the slope of the slope of the function tell you anything?

This isn't for class or anything; we were doing higher derivatives in class, and I was just wondering if there was any point/reason for them.
