b)Write the vector in terms of its magnitude and direction cosines
Find the direction angles of the given vector. Write the vector in terms of its magnitude and direction cosines as v = || v || [(cosa)i + (cos B)j + (cos y)k ] v= - 81 - 4j +8k Q = degrees (Round to the nearest tenth of a degree, if necessary.)
