Gram-Schmidt for 1, x, x^2 Must find orthonormal basis

[QUOTE="Charles Link, post: 6049537, member: 583509"] It looks like it might be mostly correct, but you got a little sloppy at the end, and your answer for ## v_3 ## should be of the form ## v_3= Ax^2+Bx+C ## where ## A , B ##, and ## C ## are also closed form expressions, and not a long decimal number. ## \\ ## Edit: And the denominator is unnecessary on the last two terms of ## v_3 ## because the functions ## v_1 ## and ## v_2 ## are normalized. ## \\ ## Additional edit: I think you got it right, but the last term you need to leave it as ## C=-\frac{\sqrt{10}}{6} ##, instead of -.52704.. which I'm sure started out as ##-\frac{\sqrt{10}}{6} ##. ## \\ ## Additional edit: I think it is necessary to normalize this final ## v_3 ## one more time. Also, I think it is not necessary to normalize the vector you are working with before you subtract out the other projections of the previous unit vectors. It makes for an extra step. [/QUOTE]
