REFRESHER EXAM 03 APPLIED MATH – HPGE – PSAD ENGR. PAUL L. LADESMA CE | ME 1 | PPE 2. If A = 3i – 5j and B = 2i + 5k, determine the cross product of A and B. A. -19 B. 0i + 25k C. 6 D. -25i – 15j + 10k SOLUTION: Note: Cross product calculations can be quite tedious to solve manually, so we'll utilize the calculator function to solve the problem. Go to: Mode 8: VCTR Select: VctA, then choose 3 axis data Note: The data includes i, j, and k, which represent the x, y, and z values, respectively. Input VctA: [3 -5 0] Repeat process for VctB: [2 0 5] Operate: VctA x Vct B = −25i − 15j + 10k Answer = −25i − 15j + 10k
