12x^2 +3

Step 1: Look at formula in formula booklet provided and write out formula.

Formula: (a+b)ⁿ= aⁿ+ ⁿc₁a^n-1b + ⁿC₂a^n-1<...

My first step would be to put all the known values on one side: ln(x) = ln(6) - ln(3) Then, using log laws, we have: ln(x) = ln(6/3) so, ln(x) = ln(2) so, x = 2

cosec(2x) + cot(2x)

CONVERT ALL COSEC/COT/SEC FUNCTIONS INTO FUNCTIONS USING SIN/TAN/COS

= 1 / (sin2x) + cos(2x) / sin(2x)

COMBINE THE TWO FRACTIONS INTO ONE

= [1...

To solve this question you need to rearrange the equation to obtain an expression in the form ax=. Make sure that whatever you do the one side of the = sign, you must also do to the other side. Firstly, s...
