Get the full course at: www.MathTutorDVD.com The student will learn what a differential equation is and why it is important in science and engineering.
ml12 Probably the concepts, and truly understanding them. Don't try to understand calculus in depth the first time you take it. You need to take analysis to really understand it, and you won't unless you're a math major. Just learn how to solve the problems, and pass. It sounds bad, but not everyone can understand it right away.. I didn't anyway, but maybe you will? I'd say the optimization problems are the hardest part. I memorized the procedures, and the homework. Learn how to do cone problems, and falling latter. There are certain problems in calculus professors always give to mess you up. Study those difficult problems. Calc II I just practiced alot, and studied ahead. I found it easier than Calc I. Physics(mechanics), and calculus are supposed to go together. Its hard to understand one without the other.
ml12 Later you'll learn the power rule, quotient, chain rules which will simplify things. There's lots to learn. The wordy stuff was hard for me to grasp right away.
BRAVO! So many oldsters out here who would have struck it out in math if we'd heard this "here's where you're going " video. BTW, COMSOL ("engineer in a box" is built on "PDEs")
so is differential equation mostly advance integration? my last math class was calc II and I'm starting differential next week. Any advice on what to focus on? what to review from calc II? thanks
if I can add to this, I can say that calculus is invented for moving things, and guess what. what do you need to describe a moving body in variable state, you need time. deferential equations can integrate time to a variable speed and give you the function to describe that movement. a moving practical with a constant speed is not a variable, yet, normal algebra can deal with that. it basically is, transferring an equation for constant to an equation for a variable. do not mix a moving particle with constant speed, with a moving particles with a variable speed. because acceleration never stabilizes on a speed, yet, that is a variable. so, calculus integrates time to a variable and give you the function too.. ..from Saudi Arabia
Man, I have to say: You're one hell of a communicator. Excellent explanation.
This guy taught me Calc II back in the day. I'm now a designer for a manufacturing company. Glad to see these are on youtube.

@starcalibre Thank you so much! Glad you like the videos!
You are an excellent teacher!!
Awesome video. Simple explanation and straight to the point.
jason is the man, he's helped me ace every math test I've ever had :D
Best teacher ever! He makes it so simple and illuminating ! Thank you sir.
Excellent job. TY!!
Very well done. Thanks.

@ptaaaaag Thank you so much!
F is also a differential of momentum wrt time(F=rate of change of momentum.)
good example, thanks.
i love differential equations!
I agree! Jason IS the man.

you are best.
thanks v nice ..
Thanks
thanks
Isnt the 2nd derivative written as d^2/d^2t^2?
My head is exploding. How do I study this? What type of problems should I do? The Khan Academy problems are very confusing.
this guy is so smart
pls how can i solve this dy/dx +6y=12
The quotient of Force (kg*m/s^2) and Mass (kg) has units (m/s^2). Acceleration is not just a number.
Otherwise good explaining!

Fuck yeah Math tutor DVD guy!
Can you take a differential of time (T) with respect to time (t) ? I'm serious.
um like dt/dt? If so that's just 1
Or you're talking about related rates
If time (T) and time (t) are just both time you can say T = t or that dT/dt = 1 when dt =/ 0
I think, yes. For example, in the relations of theoretical time, which is expected by some formula, to real one wasted. To see the deviation.

In some cases, I guess. :)
the lost knowledge have found ! Al-Khawarismi and others would love your effort !! By the way,thanks man !!
At the beginning he started well, later on he derailed !
