3:45 pretty sure 5+2=7... is that just me?

[numericalmethodsguy]

@neekoz There is an annotation on the video: 5+(1)3=8

1:24 - 1:28 made me LOL

[numericalmethodsguy]

@lmfdjtiko What made you LOL. I can use a laugh today even if it is at my expense!

If there is no 'x' in the original equation, do we just use x=0? For example, y'=y y(0)=1. When we are doing euler's method for y1 or y2, do we use x=0 in the part of the equation that says F(x,y)?

[numericalmethodsguy]

@discipleofknowledge No, you use 0*x, for your example, y'=y would be rewritten as y'=y+0*x. Sometimes this is needed to be done in some programming languages where they expect x as well as y term in f(x,y).

Thank you Dr. Kaw. This was of great help.

No one is more cherished in this world than someone who lightens the burden of another. Thank you.

Very helpful. Thanks for the video.

[exteam12]

it is easy



[thekendokid]

what a fantastic explanation!

[wangbungal]

what is the difference with this and a modified euler method?

[rohailahmedhashmi]

Thnx Teach , Appreciate your efforts ;)

[tenacious1884]

@Njzavitz you forgot that 'he' is the guy who you are replying to. lol

he teaches and he answers comments!

i learned from watching these videos than from going to class for 5 weeks.

[freazeezy]

if dy/dx=(y+2)^2+4 and y(at step 0)=y(0)=0. how do you use eulers method to find y at step 1? h=0.1
