First we have to identify that implicit differentiation is used to solve this question. We can differentiate the first the LHS first, by using the chain rule, we know that the differentiation of e^(xy) is...

Let u=2a+3, therefore du/da=2. Let y=u^5/2, therefore dy/du=5/2(u)^3/2 Hence dy/da=du/da*dy/du=2(5/2)*u^3/2=5u^3/2

In most cases, an essay question is asking you to debate a certain topic. For example, if you were to study Doctor Faustus, a question-title may be "Does Marlowe present Faustus as a character with w...

So for this question you would need to know the formula for the area of a circle. This is Area = πr^2. In this formula, r = the radius. We are given the radius in the question. So all we need to do is put...

Fermat's Principle states that light will always take the path of least travel TIME (NOT DISTANCE), at a first glance it appears that the path of least time would be a straight line from A to B, but this ...
