First of all instead ,we'll define the chain rule , thus y can be rewritten as y = f (g(x)) , where f(x) = exp (x) and g(x) = cos^2(x) + sin^2(x). Therefore let y = f(u) , dy/dx = dy/du * du/dx , which ...

With any A Level subject, it is obvious that in order to achieve a good grade, you must have the ability to recite the main principles of the topic. In sociology, you must be able to demonstrate your know...

To find the x coordinate of point P, we simply substitute in the value of y at P into the equation of the curve and solve for x = 4pi^2. (ii) To start, we can differentiate x with respect to y, by using t...

Firstly, don't panic! These questions are always either a description of a process (so you can learn it off by heart), or an analysis of information that is given to you. Although it's not advisable to wr...
