AI Thread Summary
The discussion focuses on solving for time (t) in the equation y = -4Ve^(-t/4) - 4gt + 4V when y = 0, which represents a physics problem related to the trajectory of a golf ball. The user attempts to isolate t but finds it challenging without additional information, particularly regarding the initial velocity (V). They note that if the initial velocity is zero, the problem simplifies significantly. The conversation emphasizes the need for specific values to proceed with solving for t effectively. Overall, the problem remains unsolved due to insufficient data.

Homework Statement



I put this under Pre-Calc because we're not doing Physics, we're just solving for t and don't know the algebra for it.

Solve for t

y = -4Ve^(-t/4) - 4gt + 4V


Homework Equations



V = Initial Velocity
g = Gravity
t = Time

The Attempt at a Solution



y = 0 (Physics problem, hitting a golfball and solving for t when y = 0)

-4V = -4Ve^(-t/4) - 4gt
V = Ve^(-t/4) + gt
1 = e^(-t/4) + gt/V
0 = -t/4 + ln(gt/V)

if you don't have some extra info, it looks impossible to solve for t. But, you might have as the initial velocity v=0, which of course makes it easy to solve for t. What is the exact problem, or is what you already wrote all?
 

Thread 'Family of lines that are at a distance of 5 from the origin'

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...

Thread 'Making the denominator of a certain fraction real'

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...
