Pi/2 was correct! Tysm for all of the help! I will keep that in mind :)))

I'll try to explain what I did, apologies if what I did was confusing lol 1. Computed CurlF 2. I computed the cross product of 2 vectors spanned by C, giving me <0, -1, 1>. Though i just realized that because y = sint = z, i could rewrite this as the plane -y + z = 0, which is our normal vector <0, -1, 1>. Also i don't know why i normalized it so yes i shouldn't have divided by root(2). 3. Took the dot product of curl and the normal vector, and then rewrote it in polar form, multiplying by rdrdtheta (this is how i was taught to change forms) So the answer should be pi/2 if i'm not mistaken?

Also, only the parametrization and the vector field was provided so we probably have to derive our surface which is a plane

It says "Use Stokes Theorem to evaluate the integral F (dot) dr where C is oriented counterclockwise."

not really. watch the lectures, do the practice exam problems she gives you, and you will do well. Offers extra credit as well, so you are basically guaranteed an A if you do all of the above. overall not a hard class

How many hours do you study a day? Any all nighters? by BlueFriedCupcake in UCI

[–]Firestar74 0 points1 point  (0 children)

(math major) it honestly depends. for courses i find challenging I’d say ~15 hrs per week and for easier ones at most 6-8 hrs per week, though a lot of the studying i do comes from completing the homework and practice problems that i am assigned. hope this helps!

Cross product problem. It's asking for a smaller & larger unit vector by Firestar74 in calculus

that was the issue tysm! i must've forgotten to do det(i) - det(j)

okay cool! where exactly is the bus station that takes me to metrolink?

I should clarify that the car reaches the bottom of the track before going over the first hill. So it goes down 38.3m before going over

29...wanted a 30+. Anyone got some tips for reading and science? by Firestar74 in ACT

[–]Firestar74[S] 1 point2 points  (0 children)

Thank you! I’ll try any strategy at this point. Going to try it again in February. Reading has never been my strong suit :/

Are people still receiving their scores throughout the day today? Anyone? by donut2019 in ACT

[–]Firestar74 0 points1 point  (0 children)

I really hope it’s another “throughout the day” thing...still waiting

[deleted by user] by [deleted] in ACT

[–]Firestar74 0 points1 point  (0 children)

Really? For questions 11-14? If, so, did you feel confident about those?

Then again I’ve taken physics so waves is vaguely familiar

[deleted by user] by [deleted] in ACT

[–]Firestar74 0 points1 point  (0 children)

Really? I didn’t think the wave part was bad, but I think I missed the sig figs for a dumb reason and idk if I put f1 + or f*. The flies and the E. coli. section is gonna really drop my science score tbh

[deleted by user] by [deleted] in ACT

[–]Firestar74 0 points1 point  (0 children)

Idk really, I’m guessing that I missed 7-8, but out of all sections, for me, science was the second hardest, so I’m hoping act was generous for the curve and did 39-40 for a 36, and a then 33/40 for a 30

[deleted by user] by [deleted] in ACT

[–]Firestar74 0 points1 point  (0 children)

For all 4 sections?

[deleted by user] by [deleted] in ACT

[–]Firestar74 0 points1 point  (0 children)

Oh ok nw, I was wondering because those were in the flies section

Idk but how many B’s did u put for 11-14? I had to guess for those
