SUMMARY

The equivalent of tan(t) near Pi/2 is expressed as 1/(Pi/2 - t). This conclusion arises from the fact that tan(Pi/2) is undefined, prompting the use of alternative approaches such as Taylor expansions. The discussion also suggests considering the inverse tangent function, tan^(-1)(t), as a viable method for analysis, leveraging the relationship between tangent and cotangent functions.

PREREQUISITES
  • Understanding of trigonometric functions, specifically tangent and cotangent.
  • Familiarity with Taylor series expansions.
  • Knowledge of limits and continuity in calculus.
  • Basic concepts of inverse trigonometric functions.
NEXT STEPS
  • Study Taylor series expansions for trigonometric functions.
  • Explore the properties and applications of inverse tangent functions.
  • Learn about limits involving undefined points in trigonometric functions.
  • Investigate the relationship between tangent and cotangent in detail.
USEFUL FOR

Students and educators in calculus, mathematicians exploring trigonometric limits, and anyone seeking to understand the behavior of tangent functions near critical points.

Homework Statement



How can you get an equivalent of tan(t) in the neighborhood of Pi/2?

Homework Equations



the answer is 1/(Pi/2-t)

The Attempt at a Solution



I tryed to use a Taylor's expansion but the problem is that tan(Pi/2) does not exist.



Thanks for your help!

How about doing a Taylor expansion for tan^(-1) t instead?
 
cot(pi/2) exists. And tan(x)=1/cot(x).
 
thanks guys
