Blood is primarily used to transport cells and different substances around the body. It can be divided into 4 categories of components: the blood plasma, trombocytes (platelets), leukocutes (white blood c...

One helpful method for solving questions like these is to sketch the curve in stages. First begin with the straight line y=3x+4 (taking 3x+4 from within the modulus lines) crossing the x axis at -4/3 and ...

sin(A+B) ≡ sin(A)cos(B) + sin(B)cos(A)

⇒ sin(75°) = sin(30+45)° = sin(30°)cos(45°) + sin(45°)cos(30°)

= ½ × 1/√2 + 1/√2 ×(√3)/2 = 1/(2√2) + (√3)/(2√2)

= (1+√3)/(2√2)

The main difference between a gerund and a gerundive is: - GERUND = verbal NOUN - GERUNDIVE = verbal ADJECTIVE To see what this actually means, it is perhaps easiest to look at them first in the English: ...

Firstly, take the second equation and make either x or y the subject, which means to make it either x equals or y equals. To make x the subject, we take y away from both sides giving x=8-y. Then, substitu...
