A question reads:(adsbygoogle = window.adsbygoogle || []).push({});

Let T: V-->W be a linear transformation.

a) If T is one-to-one and TR=TR1 for transformations R and R1: U -->V, show that R = R1

b) If T is onto and ST=S1T for transformations S and S1: W -->U, show that S=S1

I am sooo very lost here, and no idea where to start:(

for part a) what does it mean by TR and TR1?

just T(R): U --->V and T(R1): U ---V?

If its onto, dosn't that just mean T(R) = o and then show that R = 0?

I wont even bother with part be given that im confused with part A

Can somebody help me please

Thanks
