I believe the coefficient is 2 in 2x. Note the coefficient is the number placed before or after a variable. Ex: x2, or g7. This however is different in physics.
Answer:
Step-by-step explanation:
Let the hypotenuse of the smaller triangle be h units.
Then; from the Pythagoras Theorem.
From the smaller triangle;
and
From the second triangle, let the other other shorter leg of the second triangle be s units.
Then;
and
We now use the double angle property;
we plug in the values to obtain;
Answer:
Step-by-step explanation:
Given the differential (d/dx)(cos−1(x)), to find the equivalent formula we will differentiate the inverse function using chain rule as shown below;
let;
Therefore;
Since x = cos y from the above substitute;
Hence, gives the required proof
Assuming the cube is closed, you can use the divergence theorem:
where is the surface of the cube and is the region bounded by .
We have
so the flux is 0.
