Why 99% fail this domain problem 🛑📉

Does your brain freeze when logarithms and trigonometry team up? 🥶

Most students mess up this domain problem because they forget the Golden Rule of Inequalities: The base dictates the direction.

1️⃣ If the base is between 0 and 1, the logarithm is decreasing, so the inequality FLIPS! (Creating our shaded intervals).

2️⃣ If the base is greater than 1, it’s increasing, so the inequality STAYS! (Trapping the answer at exactly the peaks of the cosine wave).
