Welcome to Goalchemist Maths, one of the fastest-growing educational channels dedicated to helping students master mathematics through simple, powerful, and exam-oriented strategies. In today’s Youtube Shorts video, we break down a beautiful and mind-blowing trigonometry expression:

\frac{\cos 20^\circ + 8\sin 70^\circ \sin 50^\circ \sin 10^\circ}{\sin^2 80^\circ}

This expression looks complicated, but the moment you understand how trigonometric identities work together – especially complementary angles – everything becomes surprisingly elegant. Students preparing for exams like JEE Main, JEE Advanced, NEET, SSC CGL, CHSL, State PSC, Railway exams, NDA, Airforce, and even board exams often face such trigonometry simplification questions. That’s why mastering these shortcuts is extremely important.

In this video, we break the entire expression into manageable parts and simplify using powerful identities like:

✔ sin(90° – θ) = cos θ
✔ Product-to-sum formulas
✔ Complementary angle relationships
✔ Transformation identities for special angles
✔ Special results for 10°, 20°, 40°, 50°, 70°, 80°

This type of question also teaches you the deeper symmetry behind trigonometric functions. The angles might look random, but they are perfectly arranged to form a hidden identity. Once you see the trick, you can solve these questions within seconds — which is exactly what toppers do in competitive exams.

The goal of this short video is to make trigonometry simple, intuitive, and fun. The entire solution is explained in a clean, step-by-step manner to help every student understand how to approach such problems with confidence.

📌 Why this video is important?
