I know it may be more convenient for hot weather however 32 degrees for freezing sounds weird. Wouldn't it be easier if the United States were to be less stubborn and adopt to the Celsius scale so the rest of the world would understand?

Is there really a lack of "transitionary" fossils? How do we determine a fossil is indeed "transitionary"? Do you consider this a weakness in Darwin's theory, as he did?
It's a bit of an all-encompassing question, feel free to digress (within reason). :P

f(x) = 3x^(4)y - 7x^4 - 2y + 4y^3 = -3

-12x^(3)y + 28x^3
---------------------- = dy/dx
3x^4 - 2 + 12y^2

Write an equation of each horizontal tangent line to the curve.

Find the equation of the normal line at the point x = 0.

------------------------------...

For the first part I set the top part of dy/dx to 0.
-12x^(3)y + 28x^3 = 0
and I got y = 7/3
But when I go back to f(x) and substitute 7/3 for y, the function wont work. Is the answer no horizontal tangents? I think I did something wrong.

For the second part I substituted 0 into f(x) and found that y = 1.09, so I get the point (0,-1.09)
I plug those into dy/dx and I get 0. So I get a tangent slope of 0.... this contridicts what I got in the first part.

What did I do wrong?

Can anyone answer this? A spacecraft in outer space increases its velocity by firing its rockets. How can hot gases escaping from its rocket engine change the velocity of the craft when there is nothing in space for the gases to push against?
