Verifying Trigonometric Identities. This week's problem comes from an Instagram post...imagine that! 😀 I was scrolling through my feed, like I normally do, and saw @mathematicalmodels's post. Of course I was intrigued. I saw a math problem with trig and said to myself, "Oooo...what's this?" She re-posted from Canadian teen star Maitreyi Ramakrishnan who shared this old test question.
I like these kinds of trig problems. They're like puzzles to me. To solve this week's problem in completion, you need to recall the following math skills:
✔️ How to use trigonometric formulas/identities
✔️ Adding/subtracting fractions
Happy proving! Check back on Friday, May 22nd for the solution, which will be posted below ⬇️.

There is no "one way" to prove/verify this problem. In @mathematicalmodels's post, the solution was completed using the angle-addition formulas. I decided to go with the product-to-sum angle formulas just to see how it would look. Take a look for yourself...
◾️ Would you have done the problem differently??
◾️ How do feel about trigonometry...love it, hate it, or are you somewhere in the middle??
◾️ Comment below with your responses and let me know what you thought about this week's problem.
See you soon for WMP #4! 😉😁
Cheers!
