Title: exam 2 core equation question
Post by: geoftw on November 07, 2011, 04:55:52 pm

for the equation that we had to find for the core... (the log one) - second last question i think? was it to 2dp or 1dp. fml, i set my CAS calculator on a maximum of 1 dp before the exam and i forgot to set it back to normal. thankfully i used the scientific calculator for everything else...

thanks in advance :)

You lose 1 mark overall for rounding.
If you make another mistake in rounding you said only lose 1 altogether.
So goes if you make 5 mistakes in rounding you still lose 1.
