Question

if a+b+c=0 find a^2/(a^2-bc)+b^2/(b^2-ac)+c^2/(c^2-ba)

Answer 1

Ans = 3

Answer 2

~~For vectors a⃗  and b⃗ , both of the same dimensions and based at the same point, show that they satisfy

||a+b|| 2 +2||a+b|| = 2||a||2+2||b|| 2

~~Note: you must prove this identity without using components; use only vector notation and vector operations!

Calculate

dist(Q,Π)

where, Q(2,1,1), and Π is determined by the normal vector to the plane n⃗ =(2,6,9)P and the point P(8,−3,1) lies on the plane.
