evaluate the following limit using lhopitals rule. lim x→0 8 sin 6x / 7x use lhopitals rule to rewrite the given limit so that it is not an indeterminate form. lim x→0 8 sin 6x / 7x = lim x→0 () evaluate the limit. lim x→0 8 sin 6x / 7x = () (simplify your answer.)
Answer
Explanation:
Step1: Check indeterminate form
When (x\rightarrow0), (\lim_{x\rightarrow0}\frac{8\sin6x}{7x}) is in the (\frac{0}{0}) form since (\sin(0) = 0). So we can apply L'Hopital's Rule.
Step2: Differentiate numerator and denominator
The derivative of (y = 8\sin6x) using the chain - rule ((\sin u)^\prime=\cos u\cdot u^\prime) where (u = 6x) and (y^\prime=8\times\cos6x\times6 = 48\cos6x). The derivative of (y = 7x) is (y^\prime=7). So (\lim_{x\rightarrow0}\frac{8\sin6x}{7x}=\lim_{x\rightarrow0}\frac{48\cos6x}{7}).
Step3: Evaluate the new limit
Substitute (x = 0) into (\frac{48\cos6x}{7}). Since (\cos(0)=1), we have (\lim_{x\rightarrow0}\frac{48\cos6x}{7}=\frac{48\times\cos(0)}{7}=\frac{48}{7}).
Answer:
(\frac{48}{7})
