SUMMARY

The limit limx->0 (sin-1 x) / x can be solved using L'Hospital's Rule, as it presents a 0/0 indeterminate form. Alternatively, a substitution method where x = sin(p) can also be employed to simplify the problem. Both methods lead to the conclusion that the limit equals 1, aligning with the known limit limx->0 (sin x) / x = 1.

PREREQUISITES
  • Understanding of limits in calculus
  • Familiarity with L'Hospital's Rule
  • Knowledge of inverse trigonometric functions
  • Basic substitution techniques in calculus
NEXT STEPS
  • Study L'Hospital's Rule applications in calculus
  • Explore inverse trigonometric functions and their properties
  • Learn about substitution methods for solving limits
  • Review the derivation of limx->0 (sin x) / x = 1
USEFUL FOR

Students studying calculus, particularly those tackling limits and trigonometric functions, as well as educators looking for effective teaching strategies in these topics.

Your post is vague; I have no idea what level of calculus you are working on or what attempts you have made to find the solution. L'Hospital's rule certainly applies though (form 0/0).
 
You can do without L'Ho^pital's rule. Make a subsitution x=sin p. What do you get ?
