Problem 3: Let V = CR ([-1, 1]) denote the vector space of continuous real-valued
functions on the interval [−1, 1] with inner product defined as
(f,g) = [ f(x)g(x)dx.
Let
V₂ = Span{
sin(x), cos(πx), sin(2x), cos(2πx)} ≤ V
√2
Determine the orthogonal projection of the function f(x) = 1−|x| onto the subspace
V₂.

Branch of mathematics concerned with mathematical structures that are closed under operations like addition and scalar multiplication. It is the study of linear combinations, vector spaces, lines and planes, and some mappings that are used to perform linear transformations. Linear algebra also includes vectors, matrices, and linear functions. It has many applications from mathematical physics to modern algebra and coding theory.
