Answer:
infinity
Step-by-step explanation:
Given the function
Limit b⇒0 (Sin b)/b³
First substitute the value of b into the function to have
Limit b⇒0 (Sin b)/b³
= sin 0/0³
= 0/0 (Ind)
Apply lhospital rule
Limit b⇒0 (d./db(Sin b))/(d/db(b³))
=>Limit b⇒0 (cos b)/3b²
Substitute the value of b
Cos 0/3(0)²
= 1/0
= infinity
Hence the answer is infinity
