Half Yearly Exam Questions (1 Viewer)

[determine]

I thought a good thread would be to post questions we got from our half-yearly exams. One person posts, then the next person tries to answer (if they do that subject) and then posts their own question.

or, you can just post your own question without answering someone elses

its a good idea considering many of us year 11s have half yearlies coming up! (including myself)

Okay, I'll start first.

Maths
1) Differentiate: y=x^2-1/x+1
2) Solve for 0<<x <<360, tanxsinx = 3sinx - secx
3) sinx + cosx = root 2. What is tan(x/2)?
4) Solve 12cosx - 5sinx + 6 = 0
5) Solve the equation: (tanx + 1)/(1- tanx) = 1 + sin2x
6) What is the domain and range for y = x+1/(x-2)(x+3)

Chemistry
1) Account for the high melting and boiling point in covalent network structures
2) What is gravimetric analysis?
3) Describe the differences between the boiling and electrolysis of water
4) What is synthesis? What is decomposition?

Economics
1) Name the leakages and injections in the circular flow of income
2) What is specialisation?
3) Define the terms economies of scale and diseconomies of scale.
4) How does the planned economy solve the economic problem?

EDIT: sorry. I thought this thread was for revision. lol! But its likely that these questions will be in the half yearlies
