Question

Sal I have a question

Answer 1

Shoot! :)

Answer 2

lol, yes?

Answer 3

it is coming wait a sec

Answer 4

ok just type it i will be back

Answer 5

y is delta y= to the derivative of x * delta x?

Answer 6

I have no idea how to do this question lol, but:
lets say you have a change of y along the x component, this is just like saying dy/dx.
Now, dy/dx is the change with respect to x of some function y(x), f(x), or g(x),
in this case you have the function f(x), where dy/dx of the function f(x)= its derivative which is f'(x), hence:
dy/dx= f'(x) and "multiply" both sides by dx you get (delta y) same as dy= f'(x) dx

Answer 7

ok i see that :D

Answer 8

that above is all i can say, i think they kinda give you the solution, you just substitue, delta y (dy) by f'(x) dx

Answer 9

maybe.. i am not sure.. i still don't get what the question is asking.

Answer 10

yes they give the solution but I just wanted to know that question

Answer 11

cuz it seems that delta y always equals f '(x)deltax

Answer 12

When it is in the shape of this triangle i guess

Answer 13

whtvr it isnt imp

Answer 14

it is, they are just trying to visualize it for you using the pytha. theorem.
