0:00 Introduction 0:38 (sinθ)^3+(cosθ)^3 1:59 (sinθ)^4+(cosθ)^4 3:02 (sinθ)^5+(cosθ)^5 It's been a while since my last trigonometry problem, so let's solve this trigonometry problem today. Actually, this is more like a polynomial expansion/factorization problem combined with trigonometry. #algebra #trigonometry #SumsOfPowers If you're curious about sinθ - cosθ, check this video:    • If sinθ+cosθ=k, what is sinθ-cosθ? (Trigon...   ---------------------------------------------------------------------------------------- Cornerstones Of Math features quality math problems that can strengthen both your knowledge of the fundamentals of mathematics and your ability of problem-solving.
