B Sine Multiplication

AI Thread Summary
The discussion revolves around the proper approach to multiplying sine functions in equations, specifically whether to multiply all numbers first or apply the sine function to individual components. The user also questions the validity of substituting t=0.66 for t=1 in a specific equation, which lacks clarity. Participants emphasize the need for clearer expressions and examples to facilitate understanding. Additionally, there is a correction regarding the decay of Carbon-8, which does not undergo alpha emission as initially suggested. Overall, clarity in mathematical expressions and understanding the context of equations are crucial for accurate problem-solving.

TL;DR Summary
Sine Multiplication
Hi, I am doing a sine quation which has multiple numbers along the line.I was wondering when multiplying the equation out do I multiply all the numbers then sin function that number or do I sin the number beside the sine function and then multiply it out?
The equation is: sin h bt/ bt.
I also have another question, if t does not equal 1 and an equation requires that it equals one then can I use 0.66 instead of one or is the equation set for when t=1 and cannot be used with t=0.66?
 
Mathematics news on Phys.org
Lets start at the beginning:

Is this something that has to do with using Laplace transforms?

$$f(t)=\sinh(bt)=\frac{e^{bt}-e^{-bt}}{2}$$

or is your expression $$\frac{\sinh(bt)}{bt}$$ or $$\frac{\sin(hbt)}{bt}$$ ?

What does "multiple numbers along the line" mean? Also, your question would be more comprehensible if you provided an example of what you're talking about.

First, this is not an equation -- an equation expresses the equality of two expressions (or possibly more) and has an = symbol between the expressions.
Second, what you have written is too ambiguous for us to even tell what it's supposed to represent.

What equation? Why does some "equation" require that t = 1?

You're going to have to be a lot clearer in your questions if you want reasonable replies.

Sorry Im doing a continuous uniform distribution from the beta distribution using Mx= sinh(bt)/bt but Ive already fugured it out.It doesnt matter they both come out the same way.But that is not always the case. , and t=1 in a hypoerbola , but t=0.66 for me . Im doing the alpha decay of the carbon 8 to Nitrogen and C13. but eh stable alpha soes not seem to equate out.SO I am doing the uniform distribution from the beta distribution and then the continuance of the beta distribition at (x-a)^a-1(b-x)^B-1 / B(a,B) transpose (b-a)^a+B+t , a< x< b, a>0,,B > 0 and then normally distribute it, but Ive been thinking mybe I should do a student t instead first.

Carbon-8 does not decay by ##\alpha##-emission. It decays by double proton emission to beryllium-6.
 
That's great that you figured it out.

In the future, please learn to use latex to enter your math expressions. We have a simple guide. See my signature below for the link to Mathjax/latex help.

Thread 'Video on imaginary numbers and some queries'
Hi, I was watching the following video. I found some points confusing. Could you please help me to understand the gaps? Thanks, in advance! Question 1: Around 4:22, the video says the following. So for those mathematicians, negative numbers didn't exist. You could subtract, that is find the difference between two positive quantities, but you couldn't have a negative answer or negative coefficients. Mathematicians were so averse to negative numbers that there was no single quadratic...
Thread 'Unit Circle Double Angle Derivations'
Here I made a terrible mistake of assuming this to be an equilateral triangle and set 2sinx=1 => x=pi/6. Although this did derive the double angle formulas it also led into a terrible mess trying to find all the combinations of sides. I must have been tired and just assumed 6x=180 and 2sinx=1. By that time, I was so mindset that I nearly scolded a person for even saying 90-x. I wonder if this is a case of biased observation that seeks to dis credit me like Jesus of Nazareth since in reality...
Thread 'Imaginary Pythagoras'
I posted this in the Lame Math thread, but it's got me thinking. Is there any validity to this? Or is it really just a mathematical trick? Naively, I see that i2 + plus 12 does equal zero2. But does this have a meaning? I know one can treat the imaginary number line as just another axis like the reals, but does that mean this does represent a triangle in the complex plane with a hypotenuse of length zero? Ibix offered a rendering of the diagram using what I assume is matrix* notation...
