Though there are others, the two main development methodologies (i.e approaches to developing software systems) are the "Waterfall" and "Agile" approaches.

With the Waterfall ap...

Use the product rule: d/dx(uv) = uv' + u'v, with u = x^2 and v = e^(tan(x)), so that u' = 2x and v' = sec^2(x) * e^(tan(x)), and so the answer is 2x * e^(tan(x)) + x^2 * sec^2(x) * e^(tan(x)) .

Alkenes have stereoisomers because no free rotation possible around the C=C double bond, as to do so would break the pi-bond between the two atoms. which requires energy to break.

Use the formula for the surface area of revolution, which requires dy/dx. So find dy/dx = sinh(x) and substitute dy/dx and y into the formula with the limits provided in the question (2 and 6). Then evalu...
