Help me with finding tangent line

[crimson crypt]

do you know the limit derivative formula?

i don't know latex but its smth like this

lim h->0 (f(a+h)-f(a))/h

so thats the one for the derivative of the function f(a)

where h is a constant

tangent line of what?

the equation for a tangent line of f(x) at x=a is: y = f'(a)(x-a) + f(a)
