The inverse of a matrix is what we multiply that square matrix by to get the identity matrix. We’ll use the inverses of matrices to solve Systems of Equations; the inverses will allow us to get variables by themselves on one side (like “regular” algebra).

MULTIPLICATION OF A MATRIX BY A SCALAR: The product of a scalar k and a matrix X is the matrix kX, each of whose elements is k times the corresponding element of X.
Voiceover:In the last video we saw that we could take a system of two equations with two unknowns and represent it as a matrix equation where the matrix A's are the coefficients here on the left-hand side. The column vector X has our two unknown variables, S and T. Then the column vector B is essentially representing the right-hand side over here. What was interesting about it, then that would.
The 3rd Quadrant of the Problem-Solving Matrix deals with the Objective Data of your Solutions (outlined in red below). Helpful Hint: As you can see, the 3rd Quadrant is a mirror image of the 1st Quadrant (except it's for the Solutions instead of the Problem) We've used this 'mirror' design because certain aspects of your solution will mirror aspects of your problem. These 'mirror' aspects can.Math solver is an easy to use application for all students it can solve step-by-step for most high school mathematic problems like: - Finding limits - Graphing the functions - Polynomial equations: quaratic, cubic functions. - Rational and irrational equations - Solving Trigonometric equations - Solving System fo equations: can solve linear and non-linear equations, up to 5 variables - Solving.Including visual problem-solving activities, outdoor maths challenges, crack the code activities, number puzzles and more, our Year 1 and Year 2 Maths Problem-Solving worksheets are all teacher-designed and made to improve your student's analytical problem-solving skills.
