Hi :)
Integrating exponentials: Divide by the derivative of the power
a = e^3t ms-2
v = 1/3 e^3t + C
When t = 0, v = -2
-2 = 1/3 e^0 + C
= 1/3 + C (as e^0 = 1)
C = -7/3
v = 1/3 e^3t -7/3
x = (1/3)/3 e^3t -7/3t + C
= (1/9) e^3t -7/3t + C
When t = 0, x = 0
0 = (1/9) e^(0) -7/3(0)...
Hi Kendall,
What I did for memorising was further summarise my notes into dotpoints, mind maps, and timelines (if applicable). I would also try to teach a friend or even my parent about said topic to see if I understand it myself. Hope this helps!
