Vector Spaces and Projection Mappings

Please see the attached file for the fully formatted problems.

Let V be a vector space of all real continuous function on closed interval [ -1, 1]. Let Wo be a set of all odd functions in V and let We be a set of all even functions in V.
(i) Show that Wo and We are subspaces and then show that V=Wo⊕We.
(ii) Find a projection mapping onto Wo parallel to We and projection mapping onto We parallel to Wo.
(iii) Let L: V -> V be a mapping that transforms f from V into function that is given by
L f x = ∫ f t dt
Show that L is linear mapping and state whether the following is true or false:
[ ]LWo⊂We and [ ]LWe⊂Wo
(i) V=Wo⊕We then every element in V can be written as
even function odd function
fx fx f x fx f x
function even function odd function
(ii) To find a projection mapping we use:
N and P are R -submodules of M such that M =N⊕P and ϕ that is
projection mapping onto N parallel to P. Then
