Product rule: d/dx[f(x)g(x)]= f(x)d/dx[g(x)] + g(x)d/dx[f(x)]Let f(x)=x^2 and g(x)=e^xf'(x) = 2x and g'(x) = e^x Therefore,The derivative of (x^2)(e^x) = 2x(e^x) +(x^2)(e^x)

First of all select one vertex on the polygon and draw straight lines from the selected vertex to every other vertex on the polygon. In doing so this should divide the shape into 11 triangles. Using the k...

Metaphors and similes are easily confused! Both are methods of description that compare one thing to another. We find them all types of writing but most of all in poetry and fiction prose. A simile usin...
