5.2 Calculus Now

– Using properties: Given ( \int_0^3 f(x) dx = 5 ) and ( \int_3^5 f(x) dx = 2 ), find ( \int_0^5 f(x) dx ): [ \int_0^5 f = \int_0^3 f + \int_3^5 f = 5 + 2 = 7 ] 8. Connection to Next Section (5.3) Section 5.2 defines the definite integral. Section 5.3 (The Fundamental Theorem of Calculus) connects the definite integral to antiderivatives, allowing exact evaluation without limits of Riemann sums.

– Linear function (geometry): [ \int_0^2 x , dx = \textarea of triangle = \frac12(2)(2) = 2 ] 5.2 calculus
