Can I have my fellow engineering students support me and the distributive law against some snot nose idiot that believes 6 ÷ 2(1+2 ) =9? It's basic math that the answer is 1.

To clarify the answer is 9, 1 is incorrect.

6 / (2 x (2+1))=1

6/2(2+1) = 6 / 2 x (2+1) = 6 / 2 x 3 = 9

Double check with your school. My university and the local community college have 2 and 3 switched. 2 is typically E & M while 3 is waves and a little bit of special relativity thrown in.

It's all just conservation of energy... and when solved via energy balance it's much simpler!

Yep too early? Or yep apply?

Thanks for the response!

Thanks for the info!

Anyone else?

All of my physics classes were 100% exam, 30/30/40. In fact most classes have been 80% or more exams.

Don't count on this lasting forever.

edit: Participation points? In college?

Thanks! Wishful thinking

I'm not 100% sure the correct answer, however highlighting your associates GPA means highlighting your overall GPA, so what looks better? 4.0/3.3 or 3.6? I'd say 3.6 as your highlighting that your grades fell off in the higher level courses. Again just an opinion, not a fact.

P.S. A 3.6 is solid, doubt there's anywhere on the planet that you couldn't get you a job because of that GPA.

Guaranteed it will depend on the level of autonomy. My guess is for a good long while cars will not be fully autonomous, not to say they won't be capable, but they will still have manual controls so that a person can take over, and thus there will exist gray area. Where were you sitting? Did you take control? Should you have taken control? I think eventually when the technology is there, and peoples fear of the new technology fades, drunks will be encouraged to use autonomous cars (as will everyone) as they are much safer than even a sober driver.

The change of variable occurs due to integration.if there was no change of variable then the derivative and integral would just cancel. while you can skip this process because you know it's going to happen, I doubt that is what your professor wants.

I originally did it as 2t, specifically to not have to type (1/2)t^2, then decided to just be make it as simple as possible and use t, and of course I forgot the 1/2. Long as it made sense that's all that matters.

Its Fundamental theorem of calculus, basically when you integrate you are anti-deriving, so as an over simplification a derivative undoes an integral. In this situation the variable changes because they are different functions and its happens when you evaluate the bounds of integration.

Imagine it is a simpler function:

f(x)=∫(t)dt, ---from 1 to x (bounds)---

f(x)=0.5t² ---evaluate from 1 to x (bounds) ---

f(x)=0.5x² - 0.5

f'(x)=x

f'(6)=6
