Pearson Textbook Corrections

This page will be kept updated with any corrections needed for the new 2017 Pearson A Level Maths textbooks. This includes in notes, exercises, answers or Solutionbank.

I am working to change this to a Google Doc in due course.
I will not be updating the list below but instead have put a PDF on the following link:

Please send any errors you find to adamcreen@hotmail.com or tweet @adamcreen

You'll be pleased to hear that Pearson are aware of this blog and are using it before reprinting any of the textbooks, so do keep sending in the errors you spot, and you can use their email address of resourcescorrections@pearson.com if you want.

Pure Year 1

Check your ISBN:
9781 292 20826 8 is the OLD uncorrected version 1
9781 292 18339 8 is the NEW (not very corrected) version 2
You can also tell version 2 as it has the number 1 at the bottom of the spine

Mixed Exercise 2, question 2 b
In worked solutions (-1/4,25/8) should be (-1/4, -49/16)

page 39, section 3.1
amend to:
"Linear simultaneous equations in two unknowns, that are neither equivalent nor contradictory, have one set of values that will make a pair of equations true at the same time."

page 50, example 11
first line of the solution should say >2 rather than >x, in order to match the question - this is one thing that has been corrected in version 2!

page 52, exercise 3F, question 1
part b) does not make sense, as you would need both equations in the form y= before writing the inequality. You could change it to L1>L2 but that is not a proper inequality. Instead it should read
3 - 1.5x > x-5
The worked solution is also wrong in this respect

page 55, exercise 3G, question 2
the answer in the book is completely correct, but the answer in the SolutionBank has the line x>-1 as dotted rather than solid

page 55, exercise 3G, question 3
the first inequality should be < rather than > in the question - this is one thing that has been corrected in version 2!

Mixed Exercise 3, question 1
y should equal 10 not -2 in worked solutions

page 65, exercise 4B, question 1 part i
mistake in the solution online, the x value on the graph should be plotted at '-5' however they have plotted it at '-3'

page 74, exercise 4E, question 1e (ii)
mistake in worked solutions online, should be positive cube root not negative cube root

page 74, exercise 4E, question 1f (ii)
mistake in worked solutions online, should be (3,0) not (5,0)

exercise 4G question 2
X and Y mixed up in worked solution

Mixed Exercise 4, question 5
The question has 4 parts but the worked solutions have 5 parts

exercise 5G question 6 d
root 5 not root 3

page 122, exercise 6D, question 10
question poorly phrased as it asks for the range of possible values for k twice - this is one thing that has been corrected in version 2!

page 155, Mixed Ex 7, question 23
the correct answer is 3 as the working in the back forgets to square root the Pythagoras.

page 164, exercise 8C, question 2b
the worked solutions should be -80x^3 rather than x^2

page 190, exercise 9E, question 1
for part h) the answer in the back has two solutions but the first makes no sense. Angle z (at vertex B) cannot be 61.3 degrees since it is opposite the shortest side AC=4.8 cm and angle A is smaller at 45 degrees.

page 218, exercise 10E, question 2
part e) the equation is in x but the interval is given in θ

page 223, Mixed Exercise 10, question 14
the answer in the back includes 0 and 360 degrees but these are not in the interval given in the question as 0<θ
page 329, example 19
Book uses R = aP^n but then plot log P against log R, meaning gradient wrong. Question should possibly be P = aR^n.

exercise 13B question 2 a
extra 5 in first term

exercise 13B question 3 b
two different mistakes in answers in back and in worked solutions

Applied Year 1 NEW VERSION
updated 8th January 2018

Check your ISBN:
9781 292 18328 2 is the OLD uncorrected version 1
9781 292 23253 9 is the NEW corrected version 2

Please visit this site about the new version of this book
Even the new version does NOT correct the following errors:

page 36 Exercise 2F question 9
This has a rounding error. Standard deviation should be 6.29.

page 48 Section 3.4
A frequency polygon cannot be formed by joining the midpoints of the tops of the bars of a histogram

page 66 Mixed Exercise 4 question 3 part a
on the graph, amend the x axis label to Number of items (n).

page 67 Mixed Exercise 4 question 5 part c
there is a mismatch between the question and the answer
amend to:
The equation of the regression line of g on t for the remaining data is g = 44.9 – 0.47t
c) Give an interpretation of the value -0.47 in this regression equation.
The answer on page 216 should then read
c) If the temperature increases by approximately 1 oC, the number of pairs of gloves sold each month decreases by 0.47.
The Solutionbank answer for this uses the regression line of t on g as given, but has a totally different answer for part c based on 10 gloves predicting a 1.8 degree drop of temperature.

page 103 Example 4
the upper tail inequalities are incorrect, and so the critical region is wrong
It should be 0 < X < 3 and 17 < X < 40

page 223 Exercise 8A question 3 part c)
amend answer to k = 10 metres

page 227 Exercise 10B question 5 part b iii
amend the bearing to 036.9

Core Pure Year 1 (for Further Maths)

page 102 Exercise 6B question 4
matrix C should not contain a comma

exercise 6F question 5
error in question and answer

page 121 question 5
equation C should start with the variable x

page 232 Exercise 6A question 12d
the top-right element of the matrix should have the denominator 6 not 16
