Evaluate the double integral of $f(x,y)=x+y$ over the region $R$ bounded by $x=0$, $x=1$, $y=0$, and $y=2$.

Evaluate the line integral of the vector field $F(x,y)=(y,x)$ along the curve $C$, which is the line segment from $(0,0)$ to $(1,1)$.

Let C be the curve parameterized by $x=t^2$, $y=t^3$ for $0\le t\le 1$. Find the value of the line integral ${\int }_C^{}ydx$.

Find the exact length of the curve $y=\frac{1}{4}{x}^2-\frac{1}{2}\ln \left(x\right)$ for $1\le x\le 2$.

Given the parametric equations $x={\sin }^2\left(t\right)$, $y=4\cos \left(t\right)$ for $0\le t\le \pi$, what is the area enclosed by the curve and the y-axis?
