Hello everyone, i'm studying an example my professor did, and it isn't making sense to me... here is the orignal matrix:(adsbygoogle = window.adsbygoogle || []).push({});

THe oringal matrix is:

T = [3s-t]

[t].......[2t+7s]

he wants to determine if the following trnasformation is Linear.

Here is what he wrote on the board:

Why does he say:

T[x*s1]

..[x*s2]

then when he finally proves that is passes the 2nd test of linear transformations, he writes:

x*T[s1]

.....[t1]

when right up there he has s2 on the bottom, did he to say:

T[x*s1]

..[x*t1]
