SUMMARY

The limit lim(x->0) tan(3x)/sin(8x) can be solved using the trigonometric limit formula lim(x->0) sin(x)/x = 1. By rewriting tan(3x) as sin(3x)/cos(3x) and separating the terms, the expression simplifies to (1/cos(3x)) * (sin(3x)/sin(8x). As x approaches 0, 1/cos(3x) approaches 1. The remaining challenge is to evaluate sin(3x)/sin(8x), which can be resolved by multiplying and dividing by 24x, leading to a definitive solution.

PREREQUISITES
  • Understanding of trigonometric limits, specifically lim(x->0) sin(x)/x.
  • Familiarity with the properties of sine and tangent functions.
  • Basic knowledge of limit evaluation techniques in calculus.
  • Ability to manipulate algebraic expressions involving trigonometric functions.
NEXT STEPS
  • Study the derivation and applications of the limit lim(x->0) sin(x)/x.
  • Learn about the Taylor series expansions for sine and tangent functions.
  • Explore advanced limit techniques, including L'Hôpital's Rule.
  • Practice solving similar limit problems involving trigonometric functions.
USEFUL FOR

I'm trying to solve this problem

lim(x->0) tan(3x)/sin(8x)

using the formula lim(x->0) sinx/x = 1

so i did the following

tan(3x)/sin(8x)
{sin(3x)/cos(3x)}/sin8x
{1/cos(3x)} * {sin(3x)/sin(8x)}

now I know the term {1/cos(3x)} becomes 1 when you apply the limit but I have no idea how to solve the second term which is {sin(3x)/sin(8x)}...

can anyone please help

Thanks

Hint: Multiply and divide by 24x. ;)
 
I'd rather expand the fraction with the factor 24x.
 
got it... thanks guys
