WitrynaFrom the above equations, we get sin 60 degrees exact value as √3/2. In the same way, we can find the values for cos and tan ratios. Therefore, the exact value of sin 60 degrees is √3/2. Cos 0° = Sin 90° = 1. Cos 30°= Sin 60° = √3/2. Cos 45° = Sin 45° = 1/√2. Cos 60° = Sin 30° =1/2. Witryna11 lis 2024 · In mathematical, sin(x) is defined as the ratio of the opposite side to the hypotenuse, and can be written as: sin(x) = opposite side / hypotenuse. Derivative of sin square x formula. The differentiation of sin square x is equal to the product of the sine and cosine functions. This can be expressed mathematically as: d/dx (sin^2(x)) = … Witryna15 kwi 2015 · 1 Answer. Alan P.
