SUMMARY

The discussion centers on finding the limit as x approaches 0 for the expression arcsin(2x)/arcsin(3x). The user proposes a substitution where arcsin(2x) is set to y, leading to the simplification of the numerator to y. However, the denominator becomes arcsin(3/2 sin(y), which complicates the process. The user contemplates using L'Hôpital's rule due to the 0/0 indeterminate form but notes that they have not yet covered this technique in their studies.

PREREQUISITES
  • Understanding of limits in calculus
  • Knowledge of the arcsine function and its properties
  • Familiarity with substitution methods in calculus
  • Basic concepts of L'Hôpital's rule (if applicable)
NEXT STEPS
  • Study the properties of the arcsine function in detail
  • Learn about L'Hôpital's rule and its applications for indeterminate forms
  • Practice limit problems involving trigonometric functions
  • Explore substitution techniques in calculus for evaluating limits
USEFUL FOR

Students studying calculus, particularly those focusing on limits and trigonometric functions, as well as educators looking for examples of limit evaluation techniques.

I need to find Lim (x->0) arcsin(2x)/arcsin(3x)

I can do a substitution
arcsin(2x) = y => 2x = sin(y)

and get arcsin(sin(y)) for the nominator, which is equal to y.
However, for the denominator i get arcsin(3/2 sin(y)) which I'm not sure what to do with.

Am I on the right path?

Since arcsin(0)=0, you have a limit of the form 0/0...so why not use L'hopital's rule?

Well unfortunatelly i can't even tough i know it, because we haven't covered that part yet.
