Was it necessary to show the direction of motion as they did in question 6 c)???

And i thought my Tan graph was totally wrong. After seeing what itute did, i might actually get the mark.

SACs = 34%

many people havent drawn those slopefields before, and my maths teacher didnt even teach it, he said just briefly read through it ourselves, its not likely to be on the exam.

My teacher said that if anything, it'd be on Exam 2 (so I assumed that if we did get a question on it, we could use the calculator to help)

Yeah, thats what we assumed as well.

Oh well, exam 1 is dead and buried now.

At least this means its not very likely to be on Exam 2... right ? lol :(

Assume nothing

Expect everything
