Material created by students working with the School of Mathematics, Statistics & Physics E-Learning Unit at Newcastle University over the summer of 2017, to support students making the transition from school to university.

## Project activity

#### Chris Graham on Calculate the measures of central tendency for a sample 2 months, 1 week ago

Gave some feedback: Ready to use

#### Chris Graham on Calculate the measures of central tendency for a sample 2 months, 1 week ago

Saved a checkpoint:

The variable name "as" is reserved. I've updated it and the question is back working again.

#### Mario Orsi on Calculate the measures of central tendency for a sample 2 months, 1 week ago

Gave some feedback: Doesn't work

Gave some feedback: Ready to use

#### heike hoffmann on Find the equation of a line through two points - zero gradient 9 months, 1 week ago

Gave some feedback: Ready to use

#### Chris Graham on Extract common factors of polynomials 11 months, 4 weeks ago

The pattern match on line 10 of the custom function no longer appears to handle the commutativity of the expression, despite using the doCommute option. E.g. $2*(17x+2)$ is not acccepted, however $(17x+2)*2$ is.

Saved a checkpoint:

Checkpointing before looking at the problem with the user defined function mark_factorised which no longer appears to be functioning correctly.
