WebTo get a basis for the space, for each parameter, set that parameter equal to 1 and the other parameters equal to 0 to obtain a vector. Each parameter gives you a vector. So setting r = 1 and s = t = 0 gives you one vector; setting s = 1 and r = t = 0 gives you a second vector; setting t = 1 and r = s = 0 gives you a third. gmail return receipt option

Thus, once we find two linearly independent vectors in the space, they form a basis. One example of that is to choose the matrix where a = 1 and b = 0, together with the matrix where a = 0 and b = 1. gmail review filters
