We know that tan x =sin x/cos x,

so we can multiply the whole equation by cos x which gives us => 2cos^2 x =3 sin x

from the trig identity sin^2 (x)+ cos^2 (x)=1, we can sub in cos^2 (x)...

Test factors of -3 to find a root for the equation. For example, try 1, 1^3+3*1^2-1-3=0, so 1 is a root, and (x-1) is a factor. Now it's known that: (ax^2+bx+c)(x-1)=x^3+3x^2-x-3. By comparing coefficient...

The past participle agrees with the number and gender of the PDO with nothing added for masculine singular words, -e for feminine singular words, -s for masculine plural and -es for feminine plural E.g. L...

First we need to tackle the difference between 'Il est' vs. 'C'est'. Although not a huge grammatical error if chosen incorrectly, it looks impressive to examiners when a student can differentiate between ...

The long term significance of the war helped women to gain employment opportunities when the Sex Disqualifications Act was passed in 1919 which gave rights to women to enter professions like jurors, magis...
