Inverse and division of complex numbers. Four parts.
-
Matrix multiplication. Has automatically generated "unresolved" matrix product to write in the solution, which is the interesting part of this implementation.
-
Based on Chapter 8, quite loosley.Putting a pair of linear equations into matrix notation and then solving by finding the inverse of the coefficient matrix.
-
Matrix multiplication. Contains a function that will let you print the calculation steps of matrix multiplication, e.g. in the Advice.
-
Calculate matrix times vector.
-
checking by size whether two matrices can be multiplied. Student either gives size of resulting product, or NA if matrices can't be multiplied.
-
Use matrix multiplication to get an equation for k which is then to be solved.
-
Simple scalar multiplication of a general vector with the important scalars 0, 1, -1. Just the variable name is randomised.
-
Student can choose one of all possible matrix products from the matrices given. Meant for voluntary extra practice. No extensive solutions: referred to other questions for this.
-
Calculating with vectors in R4, including resolving brackets. The fixed vector size is so that a test is fair to all students.
-
Calculate matrix times vector.
-
A combination of tasks: checking which matrix products exist, calculating some of these products, calculating transpose matrices. Comparing product of transpose with transpose of product. Experiencing associativity of matrix multiplication. Not much randomisation, only in which matrix product is computed as second option.
Comprehensive solution written out in Advice.
-
First compute matrix times vector for specific vectors. Then determine domain and codomain and general formula for the matrix transformation defined by the matrix.
Randomising the number of rows in the matrix, m, makes the marking algorithm for part c) slightly complicated: it checks whether it should include the third gap or not depending on the variable m. For the correct distribution of marks, it is then necessary to do "you only get the marks if all gaps are correct". Otherwise the student would only get 2/3 marks when m=2, so the third gap doesn't appear.

Matrix multiplication. Has automatically generated "unresolved" matrix product to write in the solution.
-
To understand matrix multiplication in terms of linear combinations of column vectors.
-
Asking the student to create examples of two matrices which multiply to zero but are not themselves the zero matrix. Then getting the student to think about some features of these examples.
-
checking by size whether two matrices can be multiplied. Student either gives size of resulting product, or NA if matrices can't be multiplied.
