Q2b The other two solutions are:

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.

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.
