No it didn't just disappear, it got absorbed into the derivative on the left hand side of the equation after we multiplied through by the integrating factor. I have not done a video on integrating factors as of yet, but it's coming. It may pay to review this material.
hello again sir.. i want to ask, if the volume of substance in tank is decreasing, should the volume equation become V-initial minus with cahnge of volume? is it correct?
Hi! Happy New Year. In short yes. But it doesn't matter if you chose your sign to be a Plus because your net flow rate will be negative, and a plus and a minus still gives you a minus.
very nice breakdown!
Glad you liked it!
Merci! Very helpful!
You’re welcome!
so where did the (0.2t^2)/2 for the next part because instead of 9000 for c i got 4500
Sorry Im a little hung up on where that +y went in 7:21 it just disappeared

@@MasterWuMathematics woah.. tq tq 👍🏽👍🏽😂 sorry sir for disturbing.. sending love from Malaysia
Sorry sir but why is the initial salt quantity wasn't used?
the y(0) is the 15, so once he plugged the 0 in, c/600=15 is the equation solved to get c.
