Determine the formula for x-y-z 2. It is known that the formula for (a + b) 2 = a 2 + b 2 + 2 a b. Rewrite the expression for x-y-z 2 a s x +-y-z 2 and use the mentioned formula to simplify: x +-y-z 2 = x 2 +-y-z 2 + 2 x-y-z ⇒ x +-y-z 2 = x 2 +-y 2 +-z 2 + 2-y-z-2 x y-2 x z ⇒ x +-y-z 2 = x 2 + y 2 + z 2 + 2 y z-2 x y-2 x z. Therefore the ...

Apr 3, 2019 · What is the formula of. (x+y+z)^2 . Answer. 9 people found it helpful. swagger36. report flag outlined. (x + y + z)2 = x2 + y2 + z2 + 2xy + 2yz + 2zx. Proof: Let x + y = k then, (x + y + z)2 = (k + z)2. = k2 + 2kz + z2 (Using identity I) = (x + y)2 + 2 (x + y)z + z2. = x2 + 2xy + y2 + 2 xz + 2yz + z2. = x2 + y2 + z2 + 2xy + 2yz + 2zx (proved)
The vector algebra formulas that are involved in class 12 are as follows. For any three vectors, a, b and c: The magnitude of a = x i +y j +z k is, | a | =√ (x 2 +y 2 +z 2 ). The unit vector along a is a /| a |. The dot product is defined as: a ⋅ b = | a | | b | cos θ, where θ is the angle between the vectors a and b.
