WebThe low-tech way using barely more than matrix multiplication would be: The line y = m x is parametrised by t ⋅ ( 1 m). The line orthogonal to it is parametrised by r ⋅ ( − m 1). The line y = m x shall be fixed, the line orthogonal to it shall be reflected, so you want a matrix R with R ( 1 − m m 1) = ( 1 m m − 1), and that means
WebGiven the equation T (x) = Ax, Im (T) is the set of all possible outputs. Im (A) isn't the correct notation and shouldn't be used.
