Discussion Overview

The discussion revolves around understanding the process of dividing fractions, particularly in the context of a trigonometric expression involving cosine and sine functions. Participants explore how to manipulate the expression for further simplification.

Discussion Character

  • Conceptual clarification, Mathematical reasoning

Main Points Raised

  • One participant expresses a need for help with a trigonometric expression involving cosine and sine, indicating confusion with the notation.
  • Another participant asks for clarification on what specific aspect the original poster needs to understand.
  • A different participant suggests that the expression may need to be reduced and prompts further exploration of what can be done with it.
  • One participant explains that dividing by a fraction can be approached by inverting the fraction and multiplying, providing a specific manipulation of the expression as an example.

Areas of Agreement / Disagreement

The discussion does not appear to reach a consensus, as participants are exploring different aspects of the problem without settling on a single approach or understanding.

Contextual Notes

There are indications of confusion regarding notation and the specific steps involved in manipulating the expression, but these limitations remain unresolved.

hi, while doing trig identities I've found I am going to need to understand this..


cosx + sinx/cosx
---------------
1/cosx

sorry latex confused me so this is the best i can do :O



this is not an actuall question but just what i need help with :]

What in particular do you need to understand about it?
 
Do you need to reduce the expression? What can you do with it?
 
I presume you mean [tex]\frac{cos(x)+ \frac{sin(x)}{cos(x)}}{\frac{1}{cox(x)}[/tex]

Dividing by a fraction is the same as inverting the fraction and multiplying:
[tex](cos(x)+ \frac{sin(x)}{cos(x)})(cos(x)[/tex]. Does that help?
