It is based on approximating the area under a curve by dividing it into a series of trapezoids and summing up their areas.<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\"> <\/span><\/p>\n<p><span data-contrast=\"none\"> <\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\"> <\/span><\/p>\n<p><span data-contrast=\"none\">Basic idea behind Trapezoidal rule:<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\"> <\/span><\/p>\n<p><span data-contrast=\"none\">The basic idea behind the Trapezoidal Rule is to approximate the function by a series of straight line segments connecting consecutive points on the curve. By considering each pair of adjacent points, we can construct a trapezoid with a base formed by the line segment connecting the two points and a height equal to the difference in their function values. The area of each trapezoid is then calculated using the formula for the area of a trapezoid: <\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\"> <\/span><\/p>\n<p><span data-contrast=\"none\">Area = (base1 + base2) * height \/ 2<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\"> <\/span><\/p>\n<p><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\"> <\/span><\/p>\n<h2><b><span data-contrast=\"none\">How to apply Trapezoidal rule?<\/span><\/b><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\"> <\/span><\/h2>\n<p><span data-contrast=\"none\">To apply the Trapezoidal Rule, we divide the interval of integration [a, b] into smaller subintervals of equal width, where the width is denoted by h.

It then calculates the area of each trapezoid formed by these approximations and sums them up to estimate the integral. The Trapezoidal Rule provides a better approximation to the integral than the simple Riemann Sum by considering the average of the function values at the endpoints of each subinterval.<\/span><span data-ccp-props=\"{&quot;134233117&quot;:false,&quot;134233118&quot;:false,&quot;201341983&quot;:0,&quot;335559738&quot;:0,&quot;335559739&quot;:0,&quot;335559740&quot;:259}\"> <\/span><\/p>\n<p><span data-ccp-props=\"{&quot;134233117&quot;:false,&quot;134233118&quot;:false,&quot;201341983&quot;:0,&quot;335559738&quot;:0,&quot;335559739&quot;:0,&quot;335559740&quot;:259}\"> <\/span><\/p>\n<p><span data-contrast=\"none\">On the other hand, Riemann Sums approximate the area under the curve by dividing the interval into subintervals and using the height of rectangles to estimate the function values. The most commonly used Riemann Sum is the left Riemann Sum, which takes the left endpoint of each subinterval as the height of the rectangle. Other variations include the right Riemann Sum and the midpoint Riemann Sum. Riemann Sums provide a basic approximation to the integral and become more accurate as the number of subintervals increases.<\/span><span data-ccp-props=\"{&quot;134233117&quot;:false,&quot;134233118&quot;:false,&quot;201341983&quot;:0,&quot;335559738&quot;:0,&quot;335559739&quot;:0,&quot;335559740&quot;:259}\"> <\/span><\/p>\n<p><span data-ccp-props=\"{&quot;134233117&quot;:false,&quot;134233118&quot;:false,&quot;201341983&quot;:0,&quot;335559738&quot;:0,&quot;335559739&quot;:0,&quot;335559740&quot;:259}\"> <\/span><\/p>\n<p><span data-ccp-props=\"{&quot;134233117&quot;:false,&quot;134233118&quot;:false,&quot;201341983&quot;:0,&quot;335559738&quot;:0,&quot;335559739&quot;:0,&quot;335559740&quot;:259}\"> <\/span><\/p>\n<p><span data-contrast=\"auto\">8: What is n in trapezoidal rule?<\/span><span data-ccp-props=\"{&quot;134233117&quot;:false,&quot;134233118&quot;:false,&quot;201341983&quot;:0,&quot;335559738&quot;:0,&quot;335559739&quot;:0,&quot;335559740&quot;:259}\"> <\/span><\/p>\n<p><span data-contrast=\"auto\">Answer: In the Trapezoidal Rule, &#8216;n&#8217; represents the number of subintervals into which the interval [a, b] is divided. The larger the value of &#8216;n&#8217;, the more subintervals there are, resulting in a more accurate approximation of the definite integral. Increasing &#8216;n&#8217; decreases the width of each subinterval, allowing for a better approximation of the curve within each interval. As &#8216;n&#8217; approaches infinity, the Trapezoidal Rule converges to the exact value of the integral.<\/span><span data-ccp-props=\"{&quot;134233117&quot;:false,&quot;134233118&quot;:false,&quot;201341983&quot;:0,&quot;335559738&quot;:0,&quot;335559739&quot;:0,&quot;335559740&quot;:259}\"> <\/span><\/p>\n<p><span data-ccp-props=\"{&quot;134233117&quot;:false,&quot;134233118&quot;:false,&quot;201341983&quot;:0,&quot;335559738&quot;:0,&quot;335559739&quot;:0,&quot;335559740&quot;:259}\"> <\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>What is Trapezoidal rule?
