∠B = 90°, ∠A = 37° ∠A + ∠B + ∠C = 180° ∠C = 180° - (90° + 37°) ∠C = 180° - 127° = 53° Let the perpendicular be 3, Base be 4. Using Pythagoras theorem, P^2 + B^2 = H^2. 3^2 + 4^2 = H^2. H^2 = 9 + 16. H = H = 5. Thus, sin 37° = P/H = 3/5. Learn more: If Sin A - cos A=1,find the value of cos A+ sin A. brainly.in/question ...

2020年10月28日 · $$\sin(37°)$$ with a Taylor approximation accurate to 3 decimal digits? I know it is not a difficult question, but I have no answers of my book and so far I have only determined the Taylor approach of the umpteenth order and not approached or …

2020年12月14日 · $\begingroup$ Although, one may compute $\sin(1^\circ)$ in radical form by the triple angle formula and the radical form of $\sin(3^\circ)$, which may be found from $\sin(75^\circ-72^\circ)$. The trigonometric values in the expansion of the last expression (by sine of difference of angles) may be found geometrically.

When we find sin cos and tan values for a triangle, we usually consider these angles: 0°, 30°, 45°, 60° and 90°. It is easy to memorise the values for these certain angles. The trigonometric values are about the knowledge of standard angles for a given triangle as per the trigonometric ratios (sine, cosine, tangent, cotangent, secant and ...

2017年12月4日 · Find the value of $\\sin 37^\\circ$ without using table or calculator. I've tried using Taylor's series, but I will still need calculator. Please help me out. Thanks.

Create a table with the top row listing the angles such as 0°, 30°, 45°, 60°, 90°, and write all trigonometric functions in the first column such as sin, cos, tan, cosec, sec, cot. Step 2: Determine the value of sin

2024年4月29日 · Given: sin 37° = 3/5. We can use the trigonometric identity: sin (90° - θ) = cos θ. So, sin 53° = 3/5 (since 90° - 37° = 53°) Now, we can use another identity: tan θ = sin θ / cos θ. We know sin 53° = 3/5, and we can find cos 53° using the Pythagorean identity: cos² θ + sin² θ = 1
