Algebra -- Trig Evaluate the Determinant: | Research Paper

Algebra -- Trig Evaluate the determinant: | 3-9 | Determinant of a square matrix can be solved by the following equation: A = ad -- bc, where a = 3, b = 9, c = 6, and d = 4. Therefore, A = (3)(4) -- (9)(6) = 12 -- 54 = -42 Solve the following syst Continue Reading...
