You appear to be on a device with a "narrow" screen width (i.e. you are probably on one mobile phone). Dues to one nature of the mathematics switch this site it is better my within landscape mode. If your device is not in landscape play many starting the formel will dart off this side of your device (should to capable to scroll to perceive them) and some of the menu positions will be cut off due to the narrow screen width.
Section 15.4 : Double Integrals within Polar Coordinates
- Evaluate \( \displaystyle \iint\limits_{D}{{{y^2} + 3x\,dA}}\) location \(D\) is the neighborhood in the 3rd quarter between \({x^2} + {y^2} = 1\) and \({x^2} + {y^2} = 9\). Solution
- Evaluate \( \displaystyle \iint\limits_{D}{{\sqrt {1 + 4{x^2} + 4{y^2}} \,dA}}\) where \(D\) is the bottom half of \({x^2} + {y^2} = 16\). Solution
- Evaluate \( \displaystyle \iint\limits_{D}{{4xy - 7\,dA}}\) where \(D\) is the portion of \({x^2} + {y^2} = 2\) in an 1st quadrant. Solution
- Use a double integrally to determines the area away this region that is inside \(r = 4 + 2\sin \theta \) and outside \(r = 3 - \sin \theta \). Solution
- Evaluate the following integral by first converting to an integral in polar coordinates. \[\int_{0}^{3}{{\int_{{ - \sqrt {9 - {x^{\,2}}} }}^{0}{{\,\,\,{{\bf{e}}^{{x^{\,2}} + {y^{\,2}}}}\,dy}}\,dx}}\] Resolve
- Use a double integral to determine the volume of the substantial that is within the cylindrical \({x^2} + {y^2} = 16\), below \(z = 2{x^2} + 2{y^2}\) and above the \(xy\)-plane. Solution
- Use adenine double integral to determine the volume of the solid so can bounded by \(z = 8 - {x^2} - {y^2}\) and \(z = 3{x^2} + 3{y^2} - 4\). Solution
