1. Supose a car, going at a constant velocity, decelerates to a stop by pressing the brakes. Is the friction used to stop the car kinetic or static friction? PLEASE explain why. My teacher said the answer was static friction, but I don't understand this. Since the car is already moving and the...

I asked you a question first, so can you please answer it. The reason i asked this question is i don't see any reason why it wrong. If somebody could clearly show me why it is wrong, then i could understand why such a delta is not suitable.

i don't see how his examples applys anyway to my example or the question I just asked. Could you please just answer my question straight.

I don't get your previous example. Why can't you let delta be bigger? If delta was bigger, delta would incorporate both intervals that |f(x)-L|<E=1. Also by picking a bigger delta one can also satify the proof by saying for this delta, 0<|x-c|<delta then |f(x)-L|<E=1. Can you show why...

Why didn't you taken into account the interval (-√2,0) ? After all, in the interval (-√2,0), |f(x)-L|<E=1. Shouldn't the delta you choose take into account the intervals (-√2,0) and (0, √2). The delta you gave only applies for the x in (0, √2).

What does this statement mean. Does that mean 0<delta<sqrt 2 - 1. If so if E>1 , how can delta be more than one number.

Thank you for writing that. I proposed this example to understand the concept about limits

why are you getting so annoyed with me, I am not doing this for homework. The reason I asked all these questioned was so that i could actually understand calculus. I asked that specific question because i thought it was an interesting scenario. I tried solving but could not, that why i asked you...

I have no idea what you are doing.

I have no idea what you just said.

is the right hand rule have something to do withnature. for example in nature does a vector pointing to the right (i direction) interacting with a vector going up (j direction) always produce a vector coming in at you( k direction). If nature had a vector pointing to the right (i direction)...

thanks for that comment, i think i understand it. One last question. Can anybody solve this problem lim(x approaches 1) of x^2=1, find delta so that E=1. Can anybody solve this. Please show all of your work.

Thank you for the last comment, i understand that aspect, now can you explain this?

i don't how get how this works though by convention. Why does i * j=k why can't it equal -k.

I do read each and every one the comments, however I still don't understand sorry.
