Question

Graph both y = sin 3x and y = 5x restricted to -0.2 leq x leq 0.2. Based on the graph what is your guess for limit as (x to 0) [sin 3x]/[5x]? Then use the fact that limit as (h to 0) [sin h]/[h] = 1 and the substitution h = 3x to find limit as (x to 0) [sin 3x]/[5x].

Answer 1

I don't understand the sentence -0.2leq x leq 0.2. what does it mean?

Answer 2

IT MEANS that x greater or equal to -0.2 and less or equal than +0.02

Answer 3

i got this one
