SUMMARY

The discussion focuses on the continuity of the function P defined as P(x) = tan(π/x). It is established that P is not continuous at x = 0 and at points where x = 2/(2k + 1) for any integer k, due to the discontinuities of the tangent function. The participants emphasize the importance of understanding the domain of the function and the behavior of tan(θ) at specific values.

PREREQUISITES
  • Understanding of trigonometric functions, specifically the tangent function.
  • Knowledge of limits and continuity in calculus.
  • Familiarity with the concept of function composition.
  • Basic algebraic manipulation skills to solve equations involving π and x.
NEXT STEPS
  • Study the properties of the tangent function, particularly its discontinuities.
  • Learn about limits and continuity in calculus, focusing on piecewise functions.
  • Explore function composition and its implications for continuity.
  • Investigate the behavior of trigonometric functions at asymptotic points.
USEFUL FOR

Students studying calculus, mathematics educators, and anyone interested in understanding the continuity of trigonometric functions and their applications in analysis.

Homework Statement


Examine the continuity of
P: x -----> tan(Pi/x)

2. The attempt at a solution:
I considered fog with f=tan(x) and g=Pi/x
But the problem I have is with the domain of definition
can someone please help !
 
Physics news on Phys.org
For what values of \theta is tan(\theta) not continuous? For what values of x is \pi/x= \theta?
 
So P is not continuous on 0 and 2/2k+1 right ??
