# C4 integration watch

1. How do you integrate

dy = -ke^-0.2t
dx

yould it not be

y =
-ke^-0.2t
0.2

Man I'm rubbish at this stuff!!!
2. are you sure it is dy/dx? Not dy/dt
3. I meant dy/dt
4. There shouldn't be a negative sign before the k. The negative signs cancel out.
5. more worrying than the fact i missed that is the fact that I missed 1/0.2 = 5!!! Oh dear!! hopefully im just getting all the stupid mistakes out the way before the exam
