x ÷ y x divided by y
x = 5 x equals 5; x is equal to 5
x ≈ y x is approximately equal to y
x ≡ y x is equivalent to y; x is identical with y
x ≠ y x is not equal to y
x% x percent
∞ infinity
x ∝ y x varies as y; x is (directly) proportional to y
x ∝ 1/y x varies as one over y; x is indirectly proportional to y

Mean Valve Theorem
Theorem: If f’(x) = 0 on [a,b] The f’(x) constant on [a,b]. i.e. f(x) = f(a) for all x belong to (a,b] Proof: Assume there is a special x-value and f(x)≠f(a) Then (f(x)-f(a)) / (x-a) = m ave ≠0 There is a point C in (a,x) with f’(c) = m ave ≠0 Then this contradicts the given fact that f’(x) =0 for all x belong to (a,b) So the assumption f(x) ≠f(a) must be fake and instead, f(x)=f(a) for all x belong to (a,b].
