  1. OK i knew they were trig functions but i had no idea what they did or how to use them i have a TI-84 for this do i have to use sin(O*H) or what and you saying if i have two sides and do the inverse i can get an angle with ARCTAN yes i have seen the Tan -1 an sin -1 on my calculator and just to ask if their is a more simpler explanation for these cause i kind of get the ratio between two sides but other than that i am totally lost like the inverse i know that has to deal with the opposite regression or something like that. but functions i get them but the explanation of what they are or how to explain them is way beyond me. i took algebra 1 but other than that i have no clue.
  2. OK so i have been looking for a way to mathematically figure out how to rendezvous with anther spacecraft with out using the map as a challenge and i have been reading on Wikipedia on orbital rendezvous, and i think i have come to an partial understanding of it but i am not sure. so here is what i know that i have to do. first i have to go either higher or lower than the target, phasing orbits, and then at a certain moment i have to speed up to catch up with the target when in a matching intersection, and then after the burn i have to point retrograde on target mode on navball and fire at closest approach when i get to the separation distance. now here is the article that i have been reading and i partially understand it except for the ARC-TAN, SINE, TAN. so its just the arc tan, sine and tan that get me off cause i have no idea what they are
  3. hey guys sorry for not posting lately I haven't really had much time but I have good news and well I don't know about any bad news. the good news: Getting a new MIG/Flux welder from harbor freight. (3-4 weeks) as I have mention before I have many tools and I needed a welder for basic metal applications and that way I can start on some parts for my engine but I have been away from this thread because I haven't had any time so I haven't read any thing yet but I will soon get back on track. still looking for a job btw and it doesn't seem to be going well.
  4. if the textures for the old parts are still in the game this is just hypothetical but could you go into the game files and find the parts themselves?
  5. WHEN IS THIS GOING TO BE RELEASED!!! Finally stuff I have been asking for for ages since 2012. Yay New content!!!!!!

  7. For the helium balloon did it pop when it hit this altitude and low presure
  8. I had also had the concept of using a ballon and a video camera plus a parachute with gps locator I have been looking into kno3 and sugar mix but I would be helpful to list some more suggestions for rocket fuel
  9. Well gas I only need about 60 a month and I should be making 400 a month at 7.25 an hour 4 hours a day 5 days a week . Minus taxes do the math about a good 300
  10. I am only 16 and I get child support about 75 a week and I am trying to get a job this summer so I have to make the most of it
  11. I dont know I got to sell some stuff hoping to finish this 3d printer I am making out of cd from drives and ardunio and making a few hundred off of it
  12. Whenever I get more money.
  13. It was on suborbital trajectory but pilots experienced zero g
  14. Well orbital velocity is about 17500 mph so I think the x15 went about 5000 MPH and it got into space where you could feel no gravity I will take this Into consideration
