Trigonometrical Ratios of (180° - θ) | Relation Between All Six …
In trigonometrical ratios of angles (180° - θ) we will find the relation between all six trigonometrical ratios. Using the above proved results we will prove all six trigonometrical ratios of (180° - θ). sin (180° - θ) = sin (90° + 90° - θ) = sin [90° + (90° - θ)] = cos (90° - θ), [since sin (90° + θ) = cos θ]
Trigonometrical Ratios of (180° – θ) - CCSS Math Answers
2024年9月16日 · 1. Evaluate Sin(180° – θ)? Solution: Sin(180° – θ) = Sin (90° + 90° – θ) = Sin [90° + (90° – θ)] = Cos (90° – θ), [since Sin (90° + θ) = Cos θ] = Sin θ[since Cos (90° – θ) = Sin θ] Therefore, Sin (180° – θ) = Sin θ. 2. Evaluate Cos(180° – θ)? Cos (180° – θ) = Cos (90° + 90° – θ) = Cos [90° + (90 ...

Two ways to find the cosine of 180 degree angle
2016年1月3日 · I found a question how to find the value of cos 180, then we all know that its answer is equal to cos 0, which give us 1 as answer. I myself think that the idea of cos 180 is equal to 1 is : cos 180 =- 1. cos180∘ ≠ cos0∘ cos 180 ∘ ≠ cos 0 ∘. Think about it in terms of the unit circle to see why.
