show me what it looks like

Lute Sep 3, 2020 8:40 PM general

legorhin Sep 3, 2020 8:41 PM general

how do you need to give the answer at the end?

Lute Sep 3, 2020 8:41 PM general

I want to to print something like v0=9.6

legorhin Sep 3, 2020 8:41 PM general

so it is just printing it out?

Lute Sep 3, 2020 8:41 PM general

in the command window

Lute Sep 3, 2020 8:41 PM general

yeah

Lute Sep 3, 2020 8:42 PM general

filtering it and printing it out

Lute Sep 3, 2020 8:42 PM general

everything else I get

legorhin Sep 3, 2020 8:43 PM general

can you do this? disp(ans.v0)

Lute Sep 3, 2020 8:43 PM general

that prints this

Lute Sep 3, 2020 8:43 PM general

Phijkchu_Pikachu Sep 3, 2020 8:44 PM general

is there a simplify command

Lute Sep 3, 2020 8:44 PM general

no idea why it doesn't solve it

Lute Sep 3, 2020 8:44 PM general

that's the big issue I have been having

legorhin Sep 3, 2020 8:44 PM general

what is the data type?

Lute Sep 3, 2020 8:44 PM general

default I guess, not 100% sure what you mean by data type

Phijkchu_Pikachu Sep 3, 2020 8:44 PM general

thats right btw

Phijkchu_Pikachu Sep 3, 2020 8:44 PM general

that is 9.6

Lute Sep 3, 2020 8:44 PM general

I know it is pika....

Phijkchu_Pikachu Sep 3, 2020 8:45 PM general

then it did solve it

Lute Sep 3, 2020 8:45 PM general

I have been getting this for the last 2 hours

legorhin Sep 3, 2020 8:45 PM general

what type of field is v0?

Phijkchu_Pikachu Sep 3, 2020 8:46 PM general

Phijkchu_Pikachu Sep 3, 2020 8:46 PM general

where P(1) was his function evaluated at 1

Lute Sep 3, 2020 8:46 PM general

Lute Sep 3, 2020 8:47 PM general

dunno if this helps

Lute Sep 3, 2020 8:47 PM general

also is there a better way to define v0 and t?

Phijkchu_Pikachu Sep 3, 2020 8:47 PM general

you could specify they are real numbers

Phijkchu_Pikachu Sep 3, 2020 8:47 PM general

and probably specify they are positive

Phijkchu_Pikachu Sep 3, 2020 8:47 PM general

idk

legorhin Sep 3, 2020 8:48 PM general

pika you can force only real solutions and max one solution

Phijkchu_Pikachu Sep 3, 2020 8:49 PM general

I assumed so

legorhin Sep 3, 2020 8:53 PM general

v0t = solve([hf==h0+v0*t*sind(theta)-g/2*t*t,
       xf==x0+v0*t*cosd(theta)],
      [v0,t],'PrincipalValue',true,'Real',true);
disp(v0t);
disp(["v0 = ", double(v0t.v(1)\);
disp(["t = ", double(v0t.t(1)\);

legorhin Sep 3, 2020 8:53 PM general

assuming principle is positive

legorhin Sep 3, 2020 8:54 PM general

this would be so much easier if you could just use the free and more useful python

Lute Sep 3, 2020 8:56 PM general

it doesn't like your notation for it, I might just try to do newton raphson honestly

Lute Sep 3, 2020 8:56 PM general

I get an invalid expression error for the disp(["v0 = ", double(v0t.v(1)); line

legorhin Sep 3, 2020 8:57 PM general

you are trying to overcomplicate something just because you won't bother debugging anything

legorhin Sep 3, 2020 8:58 PM general

v0t = solve([hf==h0+v0*t*sind(theta)-g/2*t*t,
       xf==x0+v0*t*cosd(theta)],
      [v0,t],'PrincipalValue',true,'Real',true);
disp(v0t);
disp(["v0 = ", double(v0t.v(1)]);
disp(["t = ", double(v0t.t(1)]);

legorhin Sep 3, 2020 8:58 PM general

you actually have a parser there to point out typos

Lute Sep 3, 2020 9:12 PM general

still doesn't like that line

legorhin Sep 3, 2020 9:13 PM general

yeah there's a missing )

Lute Sep 3, 2020 9:15 PM general

legorhin Sep 3, 2020 9:15 PM general

then fix it

legorhin Sep 3, 2020 9:15 PM general

these are trivial typos

Dolfin Sep 3, 2020 9:58 PM general

anyways

Dolfin Sep 3, 2020 9:59 PM general

today i spent 4 hours doing statistics in analyitic chem

Bad news: the Libertarian convention has been canceled due to participants’ moms being unwilling to give them a ride.

Phijkchu_Pikachu Sep 3, 2020 11:57 PM general

BREAKING VIDEO: Michael Reinoehl, sought in fatal Portland shooting of Trump supporter, killed by officers in WA WARNING: Some may find footage disturbinghttps://t.co/0xaSxuKacl

Gent Sep 4, 2020 1:35 AM general

I can't believe the police acted as judge, jury, and executioner to stop an active shooter

Antifacist activist Michael Reinoehl was killed by police as they attempted to arrest him near Seattle, hours after he gave VICE News an interview in which he appeared to admit that he shot and killed a right-wing protester. https://t.co/SgMVu4Wgug

Spooky Phijkchu Sep 4, 2020 6:09 AM general

there's no way this is true

Spooky Phijkchu Sep 4, 2020 6:09 AM general

it's just too absurd
