\subsection*Problem 4 Evaluate ( \int_0^1 x e^x^2,dx ) using substitution. riemann integral problems and solutions pdf

\subsection*Solution 4 Let (u=x^2), (du=2x,dx) (\Rightarrow) (x,dx = du/2). When (x=0,u=0); (x=1,u=1). [ \int_0^1 x e^x^2dx = \frac12\int_0^1 e^u du = \frac12(e-1). ] # Riemann Integral: Problems and Solutions Problem 1

\subsection*Problem 5 Use the comparison property of the Riemann integral to show: [ \frac\pi6 \le \int_0^\pi/2 \frac\sin x1+x^2,dx \le \frac\pi2. ] dx) (\Rightarrow) (x
