3. 计算精确值:exact_value = math.sin(math.radians(angle)) 4. 计算近似值:approx_value = calculate_sin(angle) 5. 计算误差:error = abs(exact_value - approx_value) 6. 输出结果:print("精确值:", exact_value) print("近似值:", approx_value) print("误差:", error) 其中,calculate_sin为...
Let A=189Therefore, 5A = 90°=2A + 3A=90°=20=90°-3A 513137232Taking sine on both sides, we getsin 2A = sin (90° - 3A) = cos 3A= 2 sin A cos A = 4 cos^3 A - 3 cos A= 2 sin A cos A - 4 cos^3A + 3 cos A =0= cos A (2 sin A - 4 cos^2 A + 3) ...
Learn the value of sin 60 degrees along with other degree values like 0, 30, 45, 90, 180, 270 and 360 (degrees). Also, know the values of cosine and tangent ratios.
Find the exact value: sin(22.5∘).Trigonometric Functions:To find the value of the trigonometric functions at some point, we might need to apply the trigonometric identities. These identities are used to simplify the function and use the standard result to get the required result....
