Homework Statement evaluate the integral cos^-1 2x dx? Homework Equations The Attempt at a Solution let u = arc cos du = -1 / (sqrt 1-x^2) dv = 2x v= x^2 arc cos * x^2 - the integral of -x^2 / (sqrt 1-x^2) then i don't know what to do

thank you, i will consider those points when i write!

what do they generally look for? i need to write about how one of my hobbies and what i learned from it. english is not my first language so any tips and strategy could be useful.

i wonder if many people like me and think it physics that very hard and bio easiest.

i see that it's university dependent i am looking at dalhousie university in Canada based off this http://fya.dal.ca/Files/science.pdf it seems like i don't have to take physics classes during my b. sc journey or did i misunderstand it

i am an asian-canadian going to dalhousie univeristy in Canada thanks for your help, i will call them asap

That's re-assuring. Thanks for the help. Did you GF take physics in high school? because I am still worried physics 12 might be a pre-requisite to getting my B.Sc

I am up for the challenge, but when I don't enjoy something I find it hard to get into the material and then it makes learning it very difficult because nothing clicks. And when nothing clicks I get into stress mode which makes me frustrated and further impedes my progress. I am wondering if by...

this warrants an FML. did she have an option (i.e. between physics & geology)

damn! i hate physics. i wanted to avoid it at all costs im going for a biology major

i never took gr. 12 physics! i was simply not interested in it.. and no I am worried universities won't allow me to pursue this degree because i never took it. i took chemistry and biology up to the ap levels and also environmental science. but in my senior year i never took physics? does it...

Homework Statement At x=3 does the function y=x^3 + (x-3)^(1/3) have a vertical tangent, cusp, corner or none? The Attempt at a Solution I took the derivative y'=3x^2 + 1 / 3x^(2/3) then i replaced 3 in which gave 27 + 1 / 0 I don't understand how to come to the correct...

thank you herbert and nick i research it but don't understand that many light elements means big bang true

thank you not answer i was hoping for because its a shame we have yet to know why i will have to look at all of those papers hopefully the vocabulary will not be so difficult for me excuse my english i learning

there was a singularity, what made it expand i so confused
