If there is a circle defined by x^2+y^2=1, and another circumference with the same radius and a center point that has x between 0 and 2. How can I determine the positive y value of the centerpoint of the second circumference, taking into account that both circumferences are always touching in only 1 point (tangent cirdumferences) and an already defined x value for the center of the second circumference between 0 and 2. Also how can i determine the coordinates of the interception point? https://preview.redd.it/73b0v5nzlcvc1.png?width=645&format=png&auto=webp&s=547e97452dba1c5c171 ..read more

The way this question is worded I just can’t figure out the correct expression. How much less a number is than 8. My instinct is to say x-8 but it’s just the wording confuses me so much. submitted by /u/EvokeLife [visit reddit] [comments ..read more

My friends and I were discussing this topic for hours last night. My friends argument was that if a Triangle (presumably equilateral) is stretched over a sphere it would still be 2 dimensional and have 90° angles. My argument was that polygons have to have straight lines but I'm still not 100% sure that his idea can be completely dismissed. What do you guys think? submitted by /u/Suspicious_Sparrow9 [visit reddit] [comments ..read more

Probably an odd question in this group but i am preparing for a math assessment for a potential new job in a casino surveillance room. The job is basically watching over the table games and ensuring pay outs are correct, cheating, or other forms of it happening. Based off of my general assumptions I foresee there being a lot of pay out questions which involve like blackjack paying 3:2 or 6:5 or roulette where bets across the table have different pay out ratios etc. If anyone has tips on how to study and get the basic knowledge memorized I would greatly appreciate it!

Hello! I have been studying integrals for the past week, but there is one question that can’t get over me. Let’s start with the fact that I perfectly understood (or so I think) the logical process that led to derivatives; and, at least in the Italian books, indefinite integrals where explained to me as the inverse of derivatives: the primitive of a function is the function that has the original function as its derivative. Now we arrive to definite integrals, I understood the entire process behind how Sn and sn with n->infinity tend to the same number, that is the area under the graph. But ..read more

I'm curious how much better at math those with an undergraduate degree in math are than, say, someone with an undergraduate degree who was an average math student in high school and did not take any math in college beyond what may have been required to graduate (which, surely, would not have been very advanced). In other words, I'm just wondering how much better people in this sub think math-degree holders (and in particular, those with just an undergraduate degree in math) are than your college graduate with average mathematical knowledge. Is there an analogy you might draw to illuminate the ..read more
