This is a typical essay question, so start off by defining key terms for later use in the answer, such as what a trade-off is, and what the other macroeconomic objectives are. Then, go on the apply and an...

Firstly work out (using the sin cos tan triangle and soh cah toa) what cos 30° and tan 60° are equal to so tan 60° = √3 and cos 30° = √3 / 2 then substitute these values into the euqation giving 12 x √3 /...

To solve this question we will use the chain rule, as we can see that we have one function being applied to another, i.e sin is being applied to cos(x).

This means we are able to replace the origin...

Firstly substitute her first value into the equation so w=1 giving (3 x 1) - (1)^3 = 3 - 1= 2 so her first value for w is correct Next substitute the second value into the equation so w= -1 giving (3 x -1...
