Homework Statement
determine whether the following are linear independent sets of vectors in the vector space R*R of all functions from R to R
a)fn:=1+t+...+t^n for n=1,...4
b) sin,sin^2 ,sin^3
c)1,sin^2,cos^2
Homework Equations
The Attempt at a Solution
can i do like this for (b)(c)
sin^3=sin(sin^2)
sin^2+cos^2=1
so they are linearly dependent sets
