## nenadmatematika 4 years ago If the tangent line to y =f(x) at x =a is the same as the tangent line to y =g(x) at x = b, find two equations that must be satisfied by a and b.

I think that one is that $f \prime(a)=g \prime(b)$ what about the other one?

2. TuringTest

if the two tangent lines must be identical we have that $f(a)=g(b)$because the lines must coincide

oh I've just remembered, thank you :D
