Chemoreceptors - detect changes in co2 levels

barocreptors- detect changes in blood pressure 

mechanoreceptors - detect changes in movement

we start  y factoring and solving for each equation:

cos(x) (2cos(x) - 1) = 0 

this means: 

cos(x) = 0 and cos(x) = 1/2

from the first equation we get:   x = 90

and from...

Some of these examiners quite like asking students to find the derivative of an inverse trig or hyperbolic function to try and catch someone off guard. The best way to approach these is to first multiply ...

Expanding Rsin(x + a): Rsin(x + a) = Rsin(x)cos(a) + Rcos(x)sin(a) Comparing coefficients of sin(x), cos(x) with first expression leads to: Rsin(a) = 2, Rcos(a) = 5 Dividing these equations gives: tan(a) ...

Essentially, there are four main channels of comparison. Form, structure, language and historical/literary context. It is important to highlight the similarities between the unseen text and your wider rea...
