could someone tell me where the i^i=e^(pi/2) came from??

I have taught myself calculus 1 and 2 and I am currently working on calculus 3. I Graduate in 5 days and I will attend U of E ( I got into Rose-Hulman but I couldn't get a big enough lone to go) but I have no idea if I should major in math / get a PhD in math or get into engineering. I really...

so all that i would have to do is take 6 378.1km* ArcCos(Cos(\phi)Cos(\theta) and that would give me the distance of my great circle?

I'm in calculus 2 but the academic bowl is algebra, basic geometry and Spherical trig. i know how to find the dot product between two vectors from the little that i have done with vector algebra but i needed to find out the length by moveing on the Earth's serface. how could i do that given the...

I am the captain of my schools academic team. One of the main topics this year is Spherical trig and I can't find out how to find the shortest distance between two points on Earth given the longitude and latitude of both points. I can easily convert the points from Degree- minute- second format...

Can you do work with piecewise equations on maple?

I am thinking about maple soon and i have watched aall the movies at http://www.maplesoft.com/Products/Maple/demo/aca.aspx but at that website they are trying to sell maple so i just wanted to get a review of maple from people who have used it. also could anyone tell me any other features (good...

dose anyone know a website that has a video about how to find centroids?

ok thanks that helped a lot

thanks that makes sense but what dose the arow above pc mean?

the only equations my book gave me are; p=Ymu E=Ymc^2 KE=Ymc^2-mc^2 KE=mc^2+1/2mu^2 deltaKE+delta mc^2 E^2=p^2C^2+m^2C^4 so i don't know if i could rewrite those equations to get the ones you told me to use. if i can can you show me how? if not can you show me how to solve the problem...

Homework Statement there are 2 particles with the same mass and they undergo two different experments in expermant 1 particle 1 is moveing at .9c and particle two is at rest it wanted the KE before they hit and i got 1.29mc^2 (i checked it in my book) for experment two the total KE before...

Homework Statement a boron 14 nucleus (mass=14.02266u) is at rest splits into a electron (.00055U) and a carbon 14 (13.99995u) what are the speeds and KE for the carbon and the electron. Homework Equations i need help getting started on this so could someone help me get started...
