Homework Statement
[itex]\lim_{x\to\0} \frac{2tan^2x}{x}[/itex]
The Attempt at a Solution
[itex]\lim_{x\to\0} \frac{2tan^2x}{x} \\
= \frac{2 tanx tanx}{x} \\
= \cfrac{2 \cfrac {sin}{cos} \cfrac {sin}{cos}[/itex]
?
Edit: Oh boy none of my latex is working. :(
Homework Statement
lim x--> 0 (2tan^2x)/x
The Attempt at a Solution
lim x--> 0 (2tan^2x)/x
= [ 2 tanx (tan x) ] / x
= [ 2 (sin / cos) (sin/cos) ] / x
= [ 2 (sin^2x/cos^2x) ] / x
= [ 2sin^2x / cos^2x ] \ x
Help please. Knowing me the answer is probably pretty simple. =D
