Surjective injective bijective calculator
WebTo prove that it's surjective, though, you just need to find two vectors in R 3 whose images are not scalar multiples of each other (this means that the images are linearly independent and therefore span R 2 ). u = ( 1, 0, 0) and v = ( 0, 1, 0) work for this: M u = ( 1, 2) and M v = ( 2, 3).
