ok so this week we finished everything we needed to know about the study.
we learned how to find the area between 2 graphs
area: integral of top portion - bottom portion
what i have trouble with is determining which part is top or bottom but only when the 2 equations given are similar
for example, if f(x) is negative and g(x) is positive, more than likely f(x) will contain the top half, but if both are positive i get a little confused.
we also learned the PVA system which is AWESOME
Position is the integral of velocity
Velocity is the derivative of position
Acceleration is the derivative of velocity
with this system we can solve any problem involving P V or A (pretty cool right?) lol
Say an object is accelerating at 10t^2 m/s/s
what is the velocity?
To find velocity, take the integral of acceleration:
10/3t^3 m/s is your velocity
to sum this week up, it was very slow but we learned some pretty easy stuff so i guess all went well :P
