NettetIntegrate along the axis using the relevant bounds. A couple of hints for this particular problem: 1. You know the cross-section is perpendicular to the x-axis. A width dx, then, … NettetNow, a triangle is made up of three lines connecting the three vertices. To find the area between these three lines, you must find their equations and integrate their … have benefited a lotNettetx = 0 and x = 5. First you set up your integral ∫ 5 0 xdx. Next you find the indefinite integral. ∫xdx = 1 2 ⋅ x2 + C. Now you plugin the 5 and the 0 and solve. (1 2 ⋅ 52 + C) − (1 2 ⋅ 02 +C) = 12.5. Because this example forms a triangle, we can check the answer with the equation for the area. A = 1 2 ⋅ 5 ⋅ 5 = 12.5. boris astourne
