There are a number of pricing and non pricing a firm may use in order to seize market share, increase its total revenue and hence profits. Some pricing methods involve, a reduction in prices, predatory pr...

De Moivres theorem states that e^j(theta) = cos (theta) +jsin (theta) and this can be used to convert powered trig functions to the form of regular sines and cosines (i.e. sin^3(x) into a sum of terms inc...

A moment about a point is the product of a force applied and the distance perpendicular to the line of action of that force. So M = F*d

You should include a historians' opinion to support or contrast the argument you have made. For example, say you were arguing for a certain time period that agrarian issues led to public discontent, and t...
