    so you have the component of u along v is \[ \large \frac{||u||\;v}{||v||} \times \frac{<u, v>}{||u||\; ||v||}= \frac{v <u,v>}{||v||^2} = \frac{v <u,v>}{<v,v>}\]

    using vector law of addition we get .. the component perpendicular to V is \[V - \frac{V <U,V>}{<V,V>} \]

    |dw:1362586557753:dw| you can check for dot product ... and show be able to verify which should be perpendicular to which and ...same goes for parallel.

    Once we find u along v, we can express u as a linear combination of v and v⊥?!

    use brackets to separate it ... and don't do arithmetic.
