Discussion Overview

The discussion revolves around understanding derivatives, including how to find them, when to use them, and the meaning of symbols like \Delta. Participants explore the concept of derivatives in relation to quantities such as velocity and acceleration, as well as their application in differential equations.

Discussion Character

  • Exploratory
  • Conceptual clarification
  • Mathematical reasoning

Main Points Raised

  • One participant inquires about the process of finding derivatives and the appropriate contexts for their use, specifically questioning the meaning of the symbol \Delta.
  • Another participant references Wikipedia for a pictorial explanation of derivatives and mentions their mathematical definition, suggesting that derivatives can be used to calculate velocity from position measurements over time.
  • A comment addresses the use of all capital letters in the initial inquiry, suggesting it may be perceived as impolite.
  • One participant explains that derivatives are used to determine quantities like velocity and acceleration, which describe changes in other quantities, and provides an example involving the relationship between position and time.
  • The same participant discusses the use of derivatives in deriving differential equations, illustrating this with a mathematical example involving the relationship between position (x) and velocity (v).

Areas of Agreement / Disagreement

Participants express various viewpoints on the purpose and application of derivatives, but there is no consensus on the specific methods for finding them or the contexts in which they should be used.

Contextual Notes

Some assumptions about the mathematical background of participants may be missing, and the discussion does not resolve the nuances of when to apply derivatives or the implications of the \Delta symbol.

I WAS JUST WONDERING IF ANYBODY KNOWS HOW TO FIND DERVITIVE OR WHEN TO FIND A DERVITIVE AND WHEN DO WE USE THIS SYMBOL FOR EXAMPLE [tex]\Delta[/tex] WHAT DOES THIS MEAN AND WHEN DO YOU USE IT

Wikipedia explains what the derivative is pictorially (tangent line).

http://en.wikipedia.org/wiki/Derivative

It also gives the mathematical deffinition as well as several rules you can apply to easily get the derivative. On reason you might want to compute the derivative is to calculate the velocity if you are given a bunch of position measurements over time.
 
Writing everything in CAPTIALS is considered screaming and impolite, you might want to think about your manners if you're asking for help although we are in the "so-very-anonymous" internet.

Thanks.
 
thanks

thanks for the info :)
 
you're very welcome:smile:
 
Why To Find Derivitives

We find derivitives to get
= quantities like VELOCITY,ACCELERATION etc. .which explains the cause of change in a quantity(like change in position due to velocity,change in velocity due to acceleration & hence indirectly changing displacement due to new velocity)

= to DERIVE differential equation(i.e. equation in terms of derivatives)
let's see what i mean..

say x = t² ('x' in terms of "t")
→ v = 2t
→ t = v/2
now x = t²
→ x = (v/2)²
→ x = v²/4 ('x' in terms of derivative "v"). . .
