In plane geometry, coordinate translation and rotation, there are mutual conversions between polar and rectangular coordinates. In the Cartesian coordinate system, coordinates the translation, stress is a relative and absolute coordinates. Coordinate translation, is the result of the translational a ...
Answer to: Use polar coordinates to find the volume of the given solid. Below the paraboloid z = 32 - 2x^2 - 2y^2 and above the xy-plane By...
Answer to: Let R = \left \{(x,y)\;:\; x^2 +y^2 \leq \pi,\; x \geq 0 \right \} be a region in the plane. Use polar coordinates to evaluate the...
In polar coordinates on the Euclidean plane, the intercept form of the equation of a line that is non-horizontal, non-vertical, and does not pass through pole may be expressed as, 选择一个平面,过两平面交线上的一点作一条垂直于交线并在平面中的直线,如果这条直线与另一个平面垂直,那么两平面...
