A Level Calculated Colouring – Corrections

Thank you for all the positive comments on the A-Level Calculated colouring resource that i shared earlier in the week, I’m glad that people have used it.

I’m extremely grateful to Adam Creen (@adamcreen), Ben Plowman (@PlowMaths) and Gary Wing (@gsw71) for pointing out a few questions that had typos or needed correcting. I have now corrected the documents linked in the original post, and below are what the corrected questions should be:

  • Question 1 – “\(\int_0^2 2x+\frac{1}{2} \mathrm{d}x \)“
  • Question 11 – “The greatest root of the equation \(x^2-3x-10 = 0\).”
  • Question 15 – “The value you obtain when you evaluate \(y = 3x^3-7x+7\) at \(x = 1\)
  • Question 18 – “Absolute value of the constant term in the equation of the tangent to the curve \(y=x^3+4x^2+3\) at \(x=1\)
  • Question 50 – “For the function \(f(x)= x^2-2x+4\) what is the value \(a\) such that \(f(x+a)\) has the turning point \((-2,3)\)“
  • Question 57 – “The \(4\)th term of an arithmetic sequence such that the second term is \(6\) and the sum of the first \(5\) terms is \(55\)“.
  • Question 60 – “Given that \(t^{\frac{1}{3}} = y\) what is the coefficient of \(y^{-1}\) in the expression \(6t^{-\frac{1}{3}}\)“
  • Question 77 – “\(\frac{1}{40}\sum_{i=1}^{15}5i\)“
  • Question 83 – “The greatest value of \(v\) such that \(u\) and \(v\) solve the following pair of simultaneous equations: \( \begin{align*}2u+2v &= 16 \\uv &= 15 \end{align*} \)
  • Question 95 – “The value of the smallest \(u\) such that \(u\) and \(v\) solve the following pair of simultaneous equations: \(\begin{align*} 2u+2v &= 16 \\ uv &= 15 \end{align*} \)
  • Question 99 – “The third term of the arithmetic series with second term \(9\) and the sum of the first \(10\) terms is \(335\).”

Please let me know if you spot any other errors 🙂

  1. Speaking as a Ph.D. mathematician I wouldn’t be seen dead writing (1) like that. Would a pair of parentheses confuse your pupils?
