6. (5 points) If addition and scalar multiplication is redefined on R2 in the following way, show it is not a vector space. (21,91) + (x2, y2) = (2+ + 22,41 + y2) and c(, y) = (cx,y)
1 point Consider the set P3 = (ar3 + br2 + cr + d | a,b,c,dER) of polynomials of degree at most 3 with real coefficients. Addition and scalar multiplication of polynomials are defined as usual, i.e., =(a+d)x3 + (b + b,)x2 + (c + c')x + (d + d'), k(ax3 + bx2 + cx + d) = kar3 +kbx2 +kx + kd. Our goal is to prove that P3, with these operations, is a vector space. In this problem,...

Consider a cylindrical capacitor like that shown in Fig. 24.6. Let d = rb − ra be the spacing between the inner and outer conductors. (a) Let the radii of the two conductors be only slightly different, so that d << ra. Show that the result derived in Example 24.4 (Section 24.1) for the capacitance of a cylindrical capacitor then reduces to Eq. (24.2), the equation for the capacitance of a parallel-plate capacitor, with A being the surface area of...
