Webevaluate each integral (a) R 2 0 g(x)dx Answer: Since on [0,2] the graph of g(x) is just a straight line of slope −2 coming down from y = 4 to y = 0, the area is just the area of the triangle 1 2 2·4 = 4. Since this area is above the x-axis, definite integral equals the … WebNov 16, 2024 · In this section we will start off with a quick review of parameterizing curves. This is a skill that will be required in a great many of the line integrals we evaluate and so needs to be understood. We will then formally define the first kind of line integral we will be looking at : line integrals with respect to arc length.
