Lagrange mean value theorem ((f(b)-f(a))/(b-a) = f'(c) for some c in (a,b))
jee-mainjee-advanced
(f(b)-f(a))/(b-a) = f'(c) for some c in (a,b)
What each symbol means
| Symbol | What it stands for |
|---|---|
| c | Point where tangent parallel to chord joining (a,f(a)), (b,f(b)) |
When to use this
f continuous on [a,b], differentiable on (a,b). No need f(a)=f(b).
