Create the functionf(x)=e−x2(lnx)2. fun = @(x) exp(-x.^2).*log(x).^2; Evaluate the integral fromx=0tox=Inf. q = integral(fun,0,Inf) q = 1.9475 Parameterized Function Create the functionf(x)=1/(x3−2x−c)with one parameter,c. ...
2）用integral()函数求其定积分 >>fun=@(x)x.^5.*exp(-x).*sin(x)>>I=integral(fun,0,+Inf,'RelTol',1e-8,'AbsTol',1e-13)从计算结果来看，integral函数与int函数相比有计算误差 【int函数的语法】F = int(expr)计算expr的不定积分。int使用由symvar（expr，1）确定的默认积分变量。
Since ( -1) is constant with respect to ( x), move ( -1) out of the integral. ( ex]_1^2-(∫ )_1^2xdx) By the Power Rule, the integral of ( x) with respect to ( x) is ( 1/2x^2). ( ex]_1^2-(1/2x^2]_1^2)) Simplify the answer. ( e-3/2) The result ca...
Then ( du_2=2⋅ xe^(x^2)dx), so ( 1/2du_2=e^(x^2)xdx). Rewrite using ( u_2) and ( d)( u_2).(∫ 1/2du_2)Since ( 1/2) is constant with respect to ( u_2), move ( 1/2) out of the integral.( 1/2u_2+C)Replace all occurrences of ( u_2) with ( e^(...
