Beyond the Answer
Did you know that the value of \( \sin 30^\circ \) is a classic one to remember? It's \( \frac{1}{2} \), making problems like this much easier! Plus, \( \tan 30^\circ \) is equal to \( \frac{1}{\sqrt{3}} \) or \( \sqrt{3}/3 \) depending on how you like to express it. Use these values to simplify the expression effortlessly! Another entertaining fact is that the cotangent function is just the reciprocal of tangent. So, when you're dealing with angles like \( 50^\circ \), recognizing that \( \cot 50^\circ = \frac{1}{\tan 50^\circ} \) can make your calculations smoother and more intuitive. This little trick might save you time while solving similar trigonometric expressions!
