SUMMARY

The discussion focuses on simplifying the trigonometric expression: sin^3(x) - tan^2(x) - cot^2(x) - cos^2(x) + 1 - sin(x). The key steps identified include rewriting cos^2(x) as (1 - sin^2(x)) and substituting cot(x) with cos(x)/sin(x) and tan(x) with sin(x)/cos(x). These transformations are essential for further simplification of the expression.

PREREQUISITES
  • Understanding of trigonometric identities, specifically sin, cos, tan, and cot.
  • Familiarity with algebraic manipulation of expressions.
  • Knowledge of the Pythagorean identity: sin^2(x) + cos^2(x) = 1.
  • Ability to perform substitutions in mathematical expressions.
NEXT STEPS
  • Explore trigonometric identities and their applications in simplification.
  • Learn about the Pythagorean identities in depth.
  • Practice algebraic manipulation techniques with trigonometric functions.
  • Investigate advanced simplification techniques for trigonometric expressions.
USEFUL FOR

Students studying trigonometry, educators teaching trigonometric simplification, and anyone looking to enhance their skills in algebraic manipulation of trigonometric functions.

The Attempt at a Solution



I don't know where to go after I get to:

sin(x)[sin(x) - cos^2(x)] - tan^2(x) - cot^2(x)
 
Physics news on Phys.org
I think it might help to replace cos^2 with (1 - sin^2), and it might help to replace cot with cos/sin and tan with sin/cos
