Hi, im having some trouble with Math182_Lab_4_2007W.pdf with question 7, its giving me hints on how to set up my X and Y from the old points of x1 and y1, but my instructor forgot to teach us using the map command and im having trouble on what to do next.

i'll include my worksheet, MAT_182_-_Lab_#_4.mw

Im just on my last two questions and was wondering if you could help me again =D

So as a background to my question:

Show that dV/dt = -k * V^(2/3) given that k = 0.4836 and t is measured in minutes if the original volume of the capsule is 300 ml, how long will it take the capsule to lose half its volume?

Im doing this on maple right now and see you if guys can spot my problem or my syntax:
1. eq1 := diff(y(t), t) = -k*y(t)^(2/3)
2. dsolve(eq1, y(t)) which gives me an equation

Hi! so im working on the next problems now:

Show that dV/dt = -k * V^(2/3) given that k = 0.4836 and t is measured in minutes if the original volume of the capsule is 300 ml, how long will it take the capsule to lose half its volume?

Im doing this on maple right now and see you if guys can spot my problem or my syntax:

2. dsolve(eq1, y(t)) which gives me an equation

3. dsolve({eq1, y(0...

K, im on this question right now:

Hi, this is my first time here so hello! So im working on some questions my teacher gave to me in my class, and im having quite difficulty getting started on them, if anyone could help, that be great, thanks!

2. The first application of Newton’s method is to solve the equation
