AI Thread Summary
The discussion focuses on solving the equation 1/2 + pi/4 = (9.8/4)cos(2t) + sin(2t) for 't'. Participants express frustration with their attempts, noting that trigonometric equations often require iterative methods for solutions. A suggested approach involves rewriting the right-hand side in the form A*cos(2t + ω), utilizing trigonometric addition formulas to derive numerical values for amplitude (A) and phase (ω). This method aims to simplify the equation for easier resolution. Overall, the conversation highlights common challenges and strategies in tackling complex trigonometric equations.

Re-write the right-hand-side in the form A*cos(2t + ω), where A is the amplitude and ω is the 'phase'. Use the trigonometric addition formulas to (eventually) get numerical values for A and ω.
 

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...
