where (x0,y0,z0) are the coordinates of the point where the apexes of the two halves of the double cone meet, the constants a, b, and c are positive real numbers that define the object s general shape, and the locations of the signs (plus and minus) define the object s orientation with respect to the coordinate axes Don t get confused by the similarity between these equations and those for hyperboloids of one sheet The only difference is that the net values are all equal to 1 for the hyperboloids, and all equal to 0 for the cones 18
Question 181 What s the general symmetric equation for a straight line in Cartesian xyz space
Answer 181 Imagine that (x0,y0,z0) are the coordinates of a specific point Suppose that a, b, and c are nonzero realnumber constants The general symmetric equation of a straight line passing through (x0,y0,z0) is (x x0)/a = (y y0)/b = (z z0)/c The constants a, b, and c are called direction numbers When considered all together as an ordered pair (a,b,c), these numbers define the direction or orientation of the line with respect to the coordinate axes Question 182 What are the general parametric equations for a straight line in Cartesian xyz space
Answer 182 Let (x0,y0,z0) be the coordinates of a specific point, and suppose that a, b, and c are nonzero realnumber constants The general parametric equations for a straight line passing through (x0,y0,z0) are x = x0 + at y = y0 + bt z = z0 + ct where the parameter t can range over the entire set of real numbers As with the symmetric form, the constants a, b, and c are direction numbers that tell us how the line is orientated relative to the coordinate axes Question 183 What is meant by the expression preferred direction numbers when describing the orientation of a straight line in Cartesian xyz space Answer 183 For any line in Cartesian xyz space, there are infinitely many ordered triples that can define its orientation with respect to the coordinate axes For example, if a line has the direction numbers (a,b,c), then we can multiply all three entries by a real number other than 0 or 1, and we ll get Part Two 429
another valid ordered triple of direction numbers for that same line For the sake of simplicity and elegance, mathematicians usually reduce the direction numbers so that their only common divisor is 1, and so that at most one of them is negative Doing this produces a unique set of direction numbers in lowest terms, and these are the preferred direction numbers for the line Question 184 What are the generalized parametric equations for a parabola in Cartesian xyz space where the value of x is constant, and the curve s axis is parallel to either the y axis or the z axis Answer 184 If x is constant and the axis of the parabola is parallel to the y axis, then the curve s parametric equations are x=c y = a1t2 + a2t + a3 z=t where a1, a2, and a3 are realnumber coefficients, c is the realnumber constant value to which x is held, and t is a parameter that can range over the set of all real numbers If x is constant and the curve s axis is parallel to the z axis, then the parametric equations are x=c y=t z = a1t2 + a2t + a3 In either case, the parabola lies in a plane parallel to the yz plane Question 185 What are the generalized parametric equations for a parabola in Cartesian xyz space where the value of y is constant, and the curve s axis is parallel to either the x axis or the z axis Answer 185 If y is constant and the axis of the parabola is parallel to the x axis, then the parametric equations are x = a1t2 + a2t + a3 y=c z=t where a1, a2, and a3 are realnumber coefficients, c is the realnumber constant value to which y is held, and t is a parameter that can range over the set of all real numbers If y is constant and the curve s axis is parallel to the z axis, then the parametric equations are x=t y=c z = a1t2 + a2t + a3 In either case, the parabola lies in a plane parallel to the xz plane Review Questions and Answers Question 186 What are the generalized parametric equations for a parabola in Cartesian xyz space where the value of z is constant, and the curve s axis is parallel to either the x axis or the y axis Answer 186 If z is constant and the axis of the parabola is parallel to the x axis, then the parametric equations are x = a1t2 + a2t + a3 y=t z=c where a1, a2, and a3 are realnumber coefficients, c is the realnumber constant value to which z is held, and t is a parameter that can range over the set of all real numbers If z is constant and the curve s axis is parallel to the y axis, then the parametric equations are x=t y = a1t2 + a2t + a3 z=c In either case, the parabola lies in a plane parallel to the xy plane Question 187 What are the generalized parametric equations for a circle in Cartesian xyz space where the value of x is constant so the circle lies in a plane parallel to the yz plane, and the center of the circle lies on the x axis Answer 187 The parametric equations are x=c y = r cos t z = r sin t where r is the radius of the circle, c is the realnumber constant value to which x is held, and t is a parameter that varies continuously over a realnumber interval at least 2p units wide Question 188 What are the generalized parametric equations for a circle in Cartesian xyz space where the value of y is constant so the circle lies in a plane parallel to the xz plane, and the center of the circle lies on the y axis Part Two 431 Answer 188 The parametric equations are x = r cos t y=c z = r sin t where r is the radius of the circle, c is the realnumber constant value to which y is held, and t is a parameter that varies continuously over a realnumber interval at least 2p units wide Question 189 What are the generalized parametric equations for a circle in Cartesian xyz space where the value of z is constant so the circle lies in a plane parallel to the xy plane, and the center of the circle lies on the z axis Answer 189 The parametric equations are x = r cos t y = r sin t z=c where r is the radius of the circle, c is the realnumber constant value to which z is held, and t is a parameter that varies continuously over a realnumber interval at least 2p units wide Question 1810 Imagine a circle in Cartesian xyz space whose sets of parametric equations have one of the forms described in Answer 187 through 189 Consider the variable that s held constant Suppose that, instead of insisting that it always keep the same value, we allow that variable to follow a constant multiple of the parameter t What sort of curve will we get under these conditions Answer 1810 We ll get a circular helix centered on the axis for whichever variable follows the constant multiple of t
