Best ResponseYou've already chosen the best response.0one method is to write a 3x3 matrix write out i, j, k along the top row place the coefficients 3, 2, 5 along the second row (from first vector U) place the coefficients 1/2, 3/4, 1/10 along the second row (from second vector V) dw:1435125801371:dw
