# 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 🙂

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