Homework Statement A geologist searching for oil finds that the gravity at a certain location is 5 parts in 10^7 smaller than average. Assume that a deposit of oil is located 2000 meters directly below. Estimate the size of the deposit, assumed spherical. Take the density (mass per unit...

Ah chiro, when you say it like that it seems like common sense, lol. Thanks jbunniii. It's good to know there are some employers that don't care where the knowledge come from, I mean I'm sure you're not the only one who hires like that. Very enlightening.

Thanks guys, this gives me confidence to continue doing hobbies that I enjoy, lol I'm also just realized that programming has the potential to do the tedious computations for you, making life easier and letting me focus on more important things dealing with the problem. For example, my...

Thanks for the reply micromass :) Teaching myself programming is proving difficult, with no programming experience already under my belt. Then again that's part of the fun. It is good to know it won't be wasted if I continue, if I play my cards right lol

Hello everyone. I am going to college and plan on majoring in mathematics because my enjoyment of it is very great. Recently I have taken an interest in programming, and have been teaching myself python in my free time, and have been having fun with that lately. My question is, how well...

nah it says tanx+cotx, went over it many times. thanks guys

Homework Statement 2/(tanx+cotx)=sinx Homework Equations Double Angle Identities, Pythagorean Identities The Attempt at a Solution 2/(tanx+cotx)= 2/[(sinx/cosx)+(cosx/sinx)]= 2/[((sinx)^2+(cosx)^2)/(sinxcosx)]= 2sinxcosx/[(sinx)^2+(cosx)^2]= 2sinxcosx = sin(2x) =/=...

Thanks guys, got it.

Homework Statement 3(sin(x)^4+cos(x)^4)-2(sin(x)^6+cos(x)^6)=1 (these are sinx raised to the 4 and 6 powers, not x^4or6) Homework Equations Pythagorean Identities The Attempt at a Solution I've tried using pythagorean identities to change everything to terms of sine or...
