True or false

_ The Fundamental Theorem of Calculus links together differential and integral calculus. Let f be continuous on [(1,1)]. If so varies between a. and b, and 9(33) : f: f (t) .93157 then 9%?) = f(a:) for all :r 6 ((1,1)). It may be impossible to nd the antiderivative of f (as) in terms of elementary functions. The Change of Variables (substitution) technique for integration really undoes the Chain Rule for differentiation. The Integration by Parts technique for integration really undoes the Product Rule for differentiation
