Definite Integral of a Vector-Valued Function The definite integral of on the interval is defined by We can extend the Fundamental Theorem of Calculus to vector-valued functions. You can start by imagining the curve is broken up into many little displacement vectors: Go ahead and give each one of these displacement vectors a name, The work done by gravity along each one of these displacement vectors is the gravity force vector, which I'll denote, The total work done by gravity along the entire curve is then estimated by, But of course, this is calculus, so we don't just look at a specific number of finite steps along the curve. Marvel at the ease in which the integral is taken over a closed path and solved definitively. Since the derivative of a constant is 0, indefinite integrals are defined only up to an arbitrary constant. Any portion of our vector field that flows along (or tangent) to the surface will not contribute to the amount that goes through the surface. Calculus: Fundamental Theorem of Calculus Recall that a unit normal vector to a surface can be given by n = r u r v | r u r v | There is another choice for the normal vector to the surface, namely the vector in the opposite direction, n. By this point, you may have noticed the similarity between the formulas for the unit normal vector and the surface integral. t \right|_0^{\frac{\pi }{2}}} \right\rangle = \left\langle {0 + 1,2 - 0,\frac{\pi }{2} - 0} \right\rangle = \left\langle {{1},{2},{\frac{\pi }{2}}} \right\rangle .\], \[I = \int {\left( {{{\sec }^2}t\mathbf{i} + \ln t\mathbf{j}} \right)dt} = \left( {\int {{{\sec }^2}tdt} } \right)\mathbf{i} + \left( {\int {\ln td} t} \right)\mathbf{j}.\], \[\int {\ln td} t = \left[ {\begin{array}{*{20}{l}} Integration by parts formula: ?udv = uv?vdu?
