are 6, 3*(sinx)^2 and 2*(cosx)^2 - linearly independent ?
Can someone explain how to determine it ?
What have you tried?
You might want to make use of the Pythagorean identity (that sin^2(x) + cos^2(x) = 1).
how i use the identity to solve that problem
well, what does it mean for things to be linearly independent?
Separate names with a comma.
