PointF point2 = getPosition(point, (float) distance, currentDegree) Īnd my results are: center: PointF(490.0, 728.0) radius: 78.0 angle: 0.0Īs you can see, the degree is 0 so the point is not supposed to turn. PointF point = new PointF((float)mMiddleView.getX(), (float)mMiddleView.getY()) My values are: distance +- 70, currentDegree = 0. However when I do these calculations with for example 0 degrees it still returns another value than the original coordinates. The part to calculate the new degrees is: double theta = Math.atan2(targetPt.y - centerPt.y, targetPt.x - centerPt.x) Īnd the last part to calculate the new location would be: double x = mMiddleView.getX() + distance * s(Math.toRadians(theta)) ĭouble y = mMiddleView.getY() + distance * Math.sin(Math.toRadians(theta))

As a side note, though is sometimes called according to Wikipedia, that converts to U+25CF black circle ( ) on both Windows 7 and Anthy for Linux.

One of the problems I see is that many people don’t know how to insert symbols into their document. doesn't seem to work on the Windows 7 Japanese IME, but it looks like it does convert to U+30FB katakana middle dot () on Anthy for Linux. It’s not designed for the job, there are better options but Word is the easiest to learn and has the greatest compatibility making it easy to share documents. My first step is: distance = Math.sqrt(()*() + ()*()) Many teachers use Microsoft Word to create worksheets.
Calculate the new location with the degree (from a step back) + the degrees it needs to turn (in the images 90 degrees). Calculate the degree between the north (up) and the given point. Calculate the distance between the two points. To do this my plan was to do the following: (I also need this with different degrees such as 20 degrees). I need to calculate the coordinates of the new red dot. Now I need to calculate the new coordinates when for example the circle would turn 90 degrees to the right. That's the start with information I have. I got used to tables of contents because writers for thousands of years have been putting tables of contents first thing in books, course syllabi, and the Unix info program.I'm trying to figure out how I could be able to calculate coordinates on a circle. I guess I lack the mental capacity to memorize unordered sets of page-addresses, I am reliant on ordered table of contents to make good use of Wolfram's product. I also see that Neil Singer had already showed me that page several days ago, in this other thread. Mathematica wants me to use the mouse, because it knows every time I use the mouse, it can throw up a popup tooltip thing to block what I was about to click so instead I click on the unwanted tooltip and get sent to somewhere unwanted altogether. Even easier in unix info, just press '[' or 'l'. No keyboard-shortcut to back out of the dead end in the Mathematica documentation browser alt-left does it in every browser in the world except this one. I just tried to find a path to those pages from the front page of the documentation center, but I ran into a dead end when I tried "Documentations & Presentation -> Mathematical Typesetting". A straight list of symbols is more convenient for me than the alternatives. My little latex paper I'm writing has an index on the last page of all mathematical symbols used in the paper, scan the index, see a symbol, the index tells you what page the symbol is defined on, with a hyperlink to the definition. When I was a kid, we would just push the #2 pencil into a piece of paper, and the dot would happen. 20 more minutes killed, no dot, and no math done. Another dead end, or is it, because things in orange might be hyperlink, or they might not, and you won't know unless you take a gamble and try. Then you see "Mathematics & Operators", in orange, and under that you see a "+' and a "*" but not dot. Press random links until you find yourself on "Wolfram Language Syntax". After realizing you have made another mistake, go back to the front page of the Documentation Center. Now go to the front page of the Documentation Center. Here is how not to find the answer: Start by typing esc-d-o-t give up on that. 
Maybe I will write a program to record my long and frustrating travels through the Wolfram documentation.
