WebLet u= 2x+1, thus du= 2dx ← notice that the integral does not have a 2dx, but only a dx, so I must divide by 2 in order to create an exact match to the standard integral form. ½ du = ½ (2 dx) So the substitution is: −∫ (2x+1)⁴ dx = −∫ u⁴ (½ du) Now, factor out the ½ to get an EXACT match for the standard integral form. = −½ ...

Area between curves (video) Khan Academy
WebTo solve this problem, we first need to find the point where the two equations are equal. Doing this we find that . From this, we see that the two graphs are equal at and . We also know that for , is greater than . So to find the area between these curves we need to evaluate the integral . The solution to the integral is. WebWell, the formula for area of a circle is pi r squared, or r squared pi. So the radius is 3. So it's going to be 3 times 3, which is 9, times pi-- 9 pi. So we have 100 minus 9 pi is the area … WebFind the area between the curves and Solution. First we determine the points of intersection of the curves. We set to find the roots: Solve the quadratic equation: Thus, the cubic equation has two roots: (of multiplicity ) and The area we wish to calculate is shown in Figure below.
