Linear Algebra 2 Dualspace showing something is a Homomorphism

right @pliant igloo

you tried anything already or no ?

[pliant igloo]

ofcourse i also understand the concept of that map

but what confuses me is that it gives me a map for instance if it were to be φ(x) then i would be totally fine doing it but its just a index of φ

so Φ(x+y)=φx+y

[onyx breach]

you understand how to add two maps in this context ?

[pliant igloo]

but x+y is the index of φ

[onyx breach]

like Φ(x)+Φ(y), this is a sum of maps

[pliant igloo]

yes i understand it

[onyx breach]

yeah so what confuses you then ? i'm not sure

[pliant igloo]

i think i have it
