The value of is -3.
<h2>Procedure - Differentiability</h2><h3 /><h3>Chain rule and derivatives</h3><h3 />
We derive an expression for by means of chain rule and differentiation rule for a product of functions:
(1)
If we know that , ,<em> </em>,<em> </em> and, then we have the following expression:
The value of is -3.

<em>What is the value of </em><em> at the point </em><em>?</em>
Answer: B. We were dignified in destroying the tea. (paragraph 2)
The small bar magnet will be oriented when placed at position x by placing in a corresponding horizontal position in the magnetic field.
<h3>What is Magnetic orientation?</h3>
This is defined as the direction in which it can obtain the best magnetic properties.
The magnet is placed in an horizontal position perpendicular to the direction of the magnetic field thereby making option D the most appropriate choice.
