Question

expand this log : log x/y^6

Answer 1

Pascal's Triangle
(n = 0) 1
(n = 1) 1 1
(n = 2) 1 2 1
(n = 3) 1 3 3 1
(n = 4) 1 4 6 4 1
(n = 5) 1 5 10 10 5 1
(n = 6) 1 6 15 20 15 6 1

Use n = 6 line:
1(x^6)(y^0) + 6(x^5)(y^1) + 15(x^4)(y^2) + 20(x^3)(y^3) + 15(x^2)(y^4) + 6(x^1)(y^5) + 1(x^0)(y^6)
So more simply:
(x^6) + 6(x^5)(y) + 15(x^4)(y^2) + 20(x^3)(y^3) + 15(x^2)(y^4) + 6(x)(y^5) + (y^6)

Answer 2

thanks:) i think you might be the only one who knows how to do that!
