Trigonometrische Gleichungen lösen #3: alle Lösungen in einem Intervall (Beispiel für Sinus)

How to Math video overview at https://howtomathe.de A complete example of how to easily calculate all solutions to a trigonometric equation in a range using an anchor solution, the period length, and a sketch using symmetry considerations and adding period lengths. Why didn't I label the y-axis? Because the exact value doesn't matter. The main thing is that you can properly consider how to calculate the other digits. So, everything doesn't have to be exact, since we're not reading. And the new digits are solutions because the y-value is the same, meaning the sine component yields the same value as the first solution, and thus the equation is solved.
