Say in an exponential growth and decay question which required you to find the value of k and use it to find another value eg of T and t = something.
Instead of writing out the value of k in each step. Am I allowed to just mention that I'm using the value I've calculated in calculator memory?
Eg in 2013 q 12 c
I calculated the value of k as = (-ln(19/20))/10
Then wrote in brackets (calculator memory)
Then proceeded to continue to write k
