Action potentials are depolarisations above the threshold level traveling along a neurone, communication often evolves the action potential being transmitted from one neurone to another, this is done via ner...

Vaccinations involve introducing a small amount of dead or inactive form of a pathogen into the body. This stimulates white blood cells to produce complementary antibodies to destroy the pathogen. This is ca...

Here we are dealing with 2 concepts: trigonometry and surds.First i would make sure that the student is aware/can identify these trigonometry values.So sin45 = 1/√ 2, tan45 = 1, tan60 = √ 3Now i would insert...

First, you use the substitution u=1+e x which implies that du=e x dx. Then, you factorise e 3x = e 2x e x and replace e x dx with du. Then by rearranging, e 2x = (u-1) 2 , so you are now ready to substitute ...

There are two main methods to solve simultaneous equations. Elimination and Substitution. Usually one is easier and quicker than the other, but this is dependent upon the question you face in the exam so I w...
