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...

First thing to say is: don't panic. This does't mean that you have to know the whole text off my heart. In fact, if you did, the chances are that you wouldn't use quotes concisely enough to make your argu...
