Hum. I see. Thanks for the advice.
So you are saying what people say is true, i.e. there is no difference between statement and proposition in contemporary mathematical logic?
I see.
Thank you for that!
Apparently people are saying different things, that's why I'm confused. Like this onehttp://math.stackexchange.com/questions/440952/claim-vs-statement-vs-proposition :P
Thank you for the reply! :)
A few more questions:
1. People say that in maths logic there is not difference between statement and proposition. Is this correct?
2. They say a meaningless statement is a statement that can't be evaluated as true of false. Does such statement exist? If it does, why...
Homework Statement
I know that if a proposition can not be evaluated then it is meaningless, but how about statement like this? 4+1.
Homework EquationsThe Attempt at a Solution
I think "4+1" itself is meaningless because it can't be evaluated.
Thanks!
It's ok. So, right now I used your formula, and it ended up exactly the same as last time I did it using trig.
I got dt/dy=0.5sqrt((3+4y)/(25y-2gy^2)) dy, which even wolfram alpha couldn't give an exact solution.
I believe there is a better way to do this. Can you show me please?
I'm trying now, but still, can you show me how you would do it please?
Guess what. I used the formula you gave me and that ends up the same differential equation I got last time using trig, which I need to use a computer to calculate it. Can you help me?
That seems pretty helpful! I haven't learned to use and x and y things because I'm a high school student, but I've done stage 1 college maths so I think I can cope with that. I'll give it a try! Thank you!
1. Assume there is gravity and no external force acting on the system. A ball has an initial velocity of 5 m/s and climbs up a parabolic ramp, which is defined by y=(x^2)/3. If the ball rolls exactly along the path of ramp and energy of the ball is conserved, starting from (0,0), calculate the...
Oh. Yeah. You are correct. Not infinite but just lots. Well, infinite small is like no size but it is matter so I would like to call to infinite small.
