Rule of differentiating is to times down by the power and then reduce it by one.

Firstly we will handle the 2x^​5​:

(2*5)x^5-1=10x^​4

Here we need to get rid of either the x or the y to find one solution to start us off. By adding these equations together we get:

3x+5x+2y-2y=9+7

The y's are eliminated to l...

Start by considering what Xerophytes are, they are plants that live in dry conditions. What are the problems with dry conditions? Well, the big problem is maintaining a constant amount of water in the bod...

To find the turning points we need to find dy/dx and set it equal to zero. From there we can find the x coordinate and substitute it back into the origional equation to find the y coordinate.

Aspect in Greek refers to whether the action is continuous or completed. For example, the aorist 'ἐλυσα' I loosened, suggests that I have loosened it once and the action has been completed. Compare this t...
