If we said when x’(t) is >0 and when y’(t) is

[@ashwinsreenivasan2467]

Did we have to include units in all of our answers because it didn't specifically ask for them in the problem?. Thanks!

[@maxgarro795]

No you didn’t because it didn’t ask

[@ashwinsreenivasan2467]

@@maxgarro795 Yeah thats what I thought also. Thanks

[@sanjayvlk]

@@ashwinsreenivasan2467 Clutch I didn’t include them either so we chillin

[@seabass7610]

yes you did because rhe answers arent symbollic and they provide you units.

[@seabass7610]

you always have to answer in the context of the problem for thaat last point which means having units not just some number

[@yna418]

for b shouldnt there be absolute value for total dist traveled

[@Fliper_22]

if i forgot a negative sign for part c but my set up I wrote was correct, will I get the point?

[@LilNinja921]

You will get some, but not the one for the right answer

[@johns76251]

are the unit cm needed for part c. Its asking for coordinates

[@AllenTsaoSTEMCoach]

I don't know if they will count it.
Technically you you should put units for position but it may not be required for the scoring.

[@arhanahmed8123]

So as for c, I rounded it to -1.2, will it be considered incorrect?

[@MrRobotOne]

Yes

[@MB26535]

My calculator crapped out on me when I tried to integrate the speed function so I didn't get end up putting an actual numerical value for 2b or 2c.

[@turtle553]

I only read “show the setup” on 2b so I didn’t realize I actually needed to write the answer until after I came back to it when I finished the non-calculator portion 😭

[@maticsalt]

u needa change that yellow font color on yo website

[@ariz9264]

Should d part be (5.222,8] since it is still decreasing at 8

[@MB26535]

Yeah especially since the time interval for the position includes 8 too

[@johns76251]

yeah, thats what i put

[@AllenTsaoSTEMCoach]

Yeah that's technically true. I don't think you would be docked for excluding the 8 though.

[@accxlxrxtxr9107]

Let’s go I cooked

[@xxtayjxx]

tbh I think I went 0/4 on this one 😭
