AI Thread Summary
To solve an equation of a line with a slope of 1¼, convert the mixed number into an improper fraction, resulting in 5/4. The formula used is y - y1 = m(x - x1), where m represents the slope. The conversion process involves multiplying the whole number by the denominator and adding the numerator. An alternative method is to express the mixed number as a sum of its whole and fractional parts. Understanding this conversion is essential for applying the slope in line equations.

Homework Statement


i just want to know how i go about it when the slope contains a whole number and a fraction, i.e. 1¼

Homework Equations


y - y1 = m(x - x1)

Change the number into an improper fraction. Do you know how to do that?

For instance,
2\frac{1}{3} = \frac{7}{3}
 
i didn't no, but from the looks of it you multiply the whole number by the denominator and add the numerator

so i got it, much appreciated

Another way to think of it:

"Two and one-third" = 2+\frac{1}{3} ("and" typically means addition)

Think of a fraction with a denominator of 3 that is also equal to 2.

\frac{6}{3}+\frac{1}{3}=\frac{7}{3}

This is probably a bit more work than what's necessary, but I find it much more interesting. :biggrin:
 
I picked up this problem from the Schaum's series book titled "College Mathematics" by Ayres/Schmidt. It is a solved problem in the book. But what surprised me was that the solution to this problem was given in one line without any explanation. I could, therefore, not understand how the given one-line solution was reached. The one-line solution in the book says: The equation is ##x \cos{\omega} +y \sin{\omega} - 5 = 0##, ##\omega## being the parameter. From my side, the only thing I could...
Essentially I just have this problem that I'm stuck on, on a sheet about complex numbers: Show that, for ##|r|<1,## $$1+r\cos(x)+r^2\cos(2x)+r^3\cos(3x)...=\frac{1-r\cos(x)}{1-2r\cos(x)+r^2}$$ My first thought was to express it as a geometric series, where the real part of the sum of the series would be the series you see above: $$1+re^{ix}+r^2e^{2ix}+r^3e^{3ix}...$$ The sum of this series is just: $$\frac{(re^{ix})^n-1}{re^{ix} - 1}$$ I'm having some trouble trying to figure out what to...
