Question

F(x)=tg2 3x f'(o)....

Answer 1

F (x)=F'(x)=6tg (3x) ×1/(cos^2 (3x))
f'(0)=0,потому что tg (0)=0

Answer 2

I'm sorry, but the question seems to be incomplete or unclear.

The given function F(x) is defined as tg(2*3x), but there is no information provided about what is being asked. Also, it's not clear what is meant by "f'(o)" as there is no variable "o" defined in the problem.

Could you please provide more context or clarify the question so that I can help you better?
