  1. That's the issue. The pixels are missing from a portion of the output with the leading digit when 10 digits are displayed. That explains the discrepancy of the error showing in one expression and not another. Thanks to all who gave input.
  2. The calculator is consistently wrong with certain expressions. 5.75/0.555 has the same issue where the leading digit is off by one. Yet the issue is not present with 5.38/0.343, 75.3/0.235 Or 47.83/82.94.
  3. It's not an issue with memory. When the thousandths digit of the denominator is changed from 0 to 1, to approach sin40° the answer changes from the correct approximation of 6.14 to 5.13.
  4. I found that my hand held calculator makes a computation error. I entered the expression (4sin80°)/sin40° and my calculator returned a value of ~ 5.13. I had previously entered the expression (4sin60°)/sin40° and my calculator returned a value of ~ 5.39 so I knew there was an error. I found the expression in error. I wanted to find where this error originated. I tried several iterations but still got the the same value. I approximated the the value of the numerator and denominator and that gave a correct approximation. I continued 3.93/0.640 gave a correct approximation of 6.13, but 3.93/0.641 returned a value of ~ 5.13 with same error as above. I never had a calculator make a computational error. I'm curious if anyone has experienced this issue and if this is a way to possibly correct it?

    The Fly

    Did you identify the fly? There are many types of flies which fly faster than 5 mph. Many biting flies are particularly fast. A deer fly can fly at 25 mph.
  6. I have a class project and an idea I had deals with how people are influenced by outside factors beyond the given argument. I tested this idea with my partner for the project and generally we are in agreement about half the time which organizing data difficult. We used an online forum that is generally opinion based rather based on facts like this particular forum. My partner tends to agree with whoever has the most support from others in the forum. While I tend to agree whoever asks questions that are avoided. My partner and I both are influenced to varying degrees. I wondered if there was a way to eliminate this influence completely by using parameters and let a computer decide with a quantized output for each argument. I only have experience with Excel and Matlab this idea is probably too complicated to consider. Any suggestions?
  7. I found a method using theorem of Pappus and any of the various volume of solids and checking that the volumes are equal.
  8. In general a region bounded by the curve y=f(x) of a continuous single variable function, the x axis with some finite limits of integration. Let's work with a specific case. Suppose we have a region bounded by y=x^4, x=0 and x=1 with a centroid located at (5/6, 5/18). How do you prove that point is the centroid for the defined region?
  9. Suppose you determine a point as the centroid for a single variable function is there a method to verify that the point is indeed the centroid?
  10. Is there anything that can be seen or filmed that can pass through solid objects?
  11. I want to use the data from the game in algorithm to output as a numerical display.That requires some type of onscreen reader that can convert the live game into data that can I can enter into any various programs.
  12. I'm using the random game play of Tetris as a simplified approach to model more complicated systems. Instead of starting with zero rows of blocks, I start with nine rows as shown in the attached photo. Every game starts with a different degree of initial difficulty based on random starting position of each block and the placement of open spaces. I have a method for calculating this difficulty based on several factors. Each time a block falls and is put into position the difficultly level will change. I set ten sub-goals based when the difficulty level falls below a certain number. I want a numerical display to be able to track the time it takes to reach each sub-goal. I'm not sure how to enter the data from the game into a program to get an numerical output in real time. Any ideas?
  13. Behavior is dependent on the structure. Why define anything by dependent factors? True. Wouldn't you also say that physics deals with the structure of matter? Citation? Anyhow the surface is still defined by the structure.
  14. There are many fields in science that deal with form and structure. If the form and structure does not define what something is then what would you use to define it?
  15. Factoring is allowed in the simplification of a function to compute the limit and that reduces the limit from an undefined to a product type. The property of infinity gives rules for the various products of infinity. All of that is unnecessary because it is understood that the fasting growing term will define the limits at infinity. Can you cite these difficult bits I'm avoiding?
