Tangent is parallel, therefore (dy/dx)=0.

Find y:

y = r sin(x) = 3a(1 + cos(x))(sin(x))

Differentiate y with respect to x

dy/dx = 3a[(2cos(x) - 1...

The first characteristic is that the products are homogenous, meaning there is little difference between the quality of the goods being sold by the individual firms.

The second characteri...

As we know so far, c = f / λ. This equation comes from a much simpler version of speed = distance/ time. As the λ  (with units "m") can be seen as distance and the frequency (with units "...

Use Brady's Reagent (2,4-DNPH) to test for the presence of the C=O bond in a carbonyl compound. The formation of a yellow precipitate indicates a positive test result. Then determine the melting point ...

The passé simple is used to describe an action that belongs exclusively in the past and was not a habit, as in it happened only once in the past; whereas the imparfait is used to decribe an action that...
