Displacement is aggregate of speed over time intervals. =c+â«x0f(x)dx=c+â«0xf(x)dx= c + int_0^x f(x)dx Let's consider the equation above. The above calculates approximation of the distance traveled.  â¢  The left-hand-side gives the general form of integration. Generalizing that, for a function f(x)f(x)f(x) the approximate continuous aggregate is After you claim an answer you’ll have 24 hours to send in a draft. Abstracting this and understanding the quantities involved in integration: In =c+7x2/2=c+7x2/2= c + 7x^2//2 In each of these time intervals, the average of start and end speed can be taken as the speed during the time interval. You can help us out by revising, improving and updating Integration in the context of cause-effect relation in continuous aggregate relation:  Â»  In such a case, the effect is another algebraic expression in the variable. It is approximate, because the speed continuously changes with time, but the calculation approximates to average over 111 second intervals. But, A car is moving with speed given as a function of time v=3t2+2v=3t2+2v=3t^2+2 or an algebraic expression.  Â»  The effect is computed as continuous aggregate : the sum of change over an interval of the variable. =c+â«x0f(x)dx=c+â«0xf(x)dx=c+ int_0^x f(x) dx tâi=0.5,1,1.5,...(3i2+2)Ã0.5âi=0.5,1,1.5,...t(3i2+2)Ã0.5sum_(i=0.5,1,1.5,...)^(t) (3i^2+2)xx0.5 The speed at t=2sect=2sect=2sec is "141414 meter/sec".

Find the equation of the curve for which y" = 6x², and which passes through the points (0, 2) and (-1, 3). & \int {{{\cos }^{ - 1}}\left( {2x} \right)} dx = x{\cos ^{ - 1}}\left( {2x} \right) + 2\int {\frac{{\left( { - 1/8} \right)dt}}{{\sqrt t }}} \cr and nâi=11=nâi=1n1=nsum_(i=1)^(n) 1 = n â displacement =limnâânâi=1v(ixn)xn=limnâââi=1nv(ixn)xn=lim_(n->oo) sum_(i=1)^n v((i x)/n) x/n, Â» Integration or integral of a function & \int {{{\cos }^{ - 1}}\left( {2x} \right)} dx = x{\cos ^{ - 1}}\left( {2x} \right) - \frac{1}{4}\int {{t^{ - 1/2}}} dt \cr Then, it can be easily solved based on some property of the limit of summation. can it be given without a numerical value for ttt. To get substitute t=2t=2t=2 in the formula for vvv. Â» The cause is calculated as a function of an algebraic expression in a variable.
