This question relies partially on remembering the trigonometric identities, csc(x) = 1/(sin(x)) and cot(x) = 1/(tan(x)) = cos(x)/sin(x). Plugging these values into the equation, we want to find Lim((1-...
Force Filed analysis is a decision making tool analysing the forces for and against a decision or change. It is divided into driving forces (advantages) and restraining forces (disadvantages). A weight...
This question is an example of the chain rule for differentiating.
Firstly, identify the inner function. In this case, it is x2 - 3x. This function must be differentiated firs...
As with any question involving sines and cosines, consider complex numbers as a likely way to find the answer. For this particular kind of question, where sin/cos of a multiple of x is needed in terms ...
The integral of sine is pretty easy to remember as it is -cos + C. However you need to be able to prove this, without using the integral of cosine. This method uses sines exponential form.
