Question

May someone help me comprehend what to do for Trig Function Limits:
The limit as h approaches 0: (tan(x(x+h))-tan(2x))/h

Answer 1

\[\frac{ \tan(2(x+h))-\tan(2x) }{ h }\]
The answer is: \[2\sec^2(2x)\]
Initially I thought to distribute and:\[\frac{ \tan(2x)+\tan(2h)-\tan(2x) }{ h }\]

Answer 2

you cant distribute

Answer 3

Mmk, in which case, wat do? lol
