Applications of Differential Calculus L’Hospital’s Rule
Consider a limit of the form i.e. e.g.
What will the graphs look like if this part is magnified? f(x) = tan2x g(x) = sin x
f(x) g(x) x f(x) = tan2x g(x) = sin x When x 0, f(x) xf '(x) g(x) xg'(x)
L'Hospital’s Rule For a limit of the form i.e. If exists, then
Consider a limit of the form When x a, (in the form )
Example The graph of ln x
y = ln x Back
