Question 30 – Solve the simultaneous equation using simple Excel program : r + s – t = 7, 2r – s = 0, 3r + 2t = 15. Explain the use of functions of MINVERSE and MMULT together with the keyboard C (Ctrl) + S (Shift) + E (Enter).
Answer Posted / kang chuen tat (malaysia - pen
Answer 30 : By using Microsoft Excel, r = 3.22, s = 6.44, t = 2.67. MINVERSE, or =minverse is used to inverse the 3 x 3 matrix with constants of r, s, t. MMULT, or =mmult can be used to obtain the answers by functions (inversed matrix of 3 x 3, constants of 7 and 0 and 15). CSE is an Excel function to perform quick calculations for the cells.
