It looks like the min and max occur when sin = 0 (0 or 180).

How do I demonstrate gravitational influence mathematically?
mathematic replied to Butch's topic in Classical Physics
Use inverse squarer relationship. Your description doesn't describe the motion of the first two relative to the third. 
It will depend on where the observer is relative to the meteorites. Speed of sound is not subject to Lorentz transformation.

Zeno's paradox goes away when time is considered.

What type of scientist creates antivenoms?
mathematic replied to chrismackey1972's topic in Other Sciences
Why is the name of a particular specialty important? I presume venomology is narrower than toxicology. Try Google. 
How about "unmasking"?

The link appears to be a list of numbers  no picture?

Draw a picture!

Square root and power of a negative number
mathematic replied to neonwarrior's topic in Linear Algebra and Group Theory
My statement is about all (including complex) numbers. 
Square root and power of a negative number
mathematic replied to neonwarrior's topic in Linear Algebra and Group Theory
Every number (except 0) has two square roots. Using the convention (ignore negative root) leads to these kinds of problems. l 
Help with some Lebesgue measure problems
mathematic replied to john33's topic in Analysis and Calculus
Nonempty open sts must have positive measure, so your approach to the first question is correct. The second question is almost from the definition. 
Lebesgue measure and Lebesgue integral
mathematic replied to fmaths's topic in Analysis and Calculus
The second and third easily false. The two function could agree on the rationals, but not elsewhere. You need to use another deliminator for Latex $ doesn't work here [math] and [math] with / work. 
Is it possible that round moving have more strong impulse?
mathematic replied to altaylar2000's topic in Classical Physics
Looking at the original question (I have not plowed through the responses), the ball on chain can hit harder than the hammer because it can be made to go much faster before release. 
Pure speculation. High wind conditions could lead to evolution of very sturdy thick trunk trees which would mitigate winds and allow small (compared to tree size) animals to evolve.

sqrt(x)= 1 , no soln. ?
mathematic replied to IndianScientist's topic in Linear Algebra and Group Theory
Mathematically sqrt(1) has two solutions +1 and 1. There is a convention that only +1 is allowed and the program may be set up to follow the convention. 
The nature of the electric current (Hypothesis)
mathematic replied to altaylar2000's topic in Speculations
The point I am making is the speed of the electrons is irrelevant to electricity working. 
The nature of the electric current (Hypothesis)
mathematic replied to altaylar2000's topic in Speculations
Most households use AC where the electrons jiggle in place. 
I don't get it!

Is there a question? What are N, x, y?

mereotopological objective probability
mathematic replied to Prof Reza Sanaye's topic in Other Sciences
I hate to say this, but it sounds like meaningless wordplay. 
mereotopological objective probability
mathematic replied to Prof Reza Sanaye's topic in Other Sciences
Sorry! Completely strange to me. 
mereotopological objective probability
mathematic replied to Prof Reza Sanaye's topic in Other Sciences
mereotopological  Did you invent this word? What does it supposed to mean? 
I agree with Fermi. Interstellar distances are a the main problem.
