$$0 + \sqrt{3} \cos(30) + 3 \cdot 0,48480962024633706 \cdot 2,062665339627314 - x \frac{1}{y}$$

Ottieni il valore di \cos(30) dalla tabella dei valori trigonometrici.

$$0+\sqrt{3}\times \frac{\sqrt{3}}{2}+3\times 0,48480962024633706\times 2,062665339627314-x\times \frac{1}{y}$$

Esprimi \sqrt{3}\times \frac{\sqrt{3}}{2} come singola frazione.

$$0+\frac{\sqrt{3}\sqrt{3}}{2}+3\times 0,48480962024633706\times 2,062665339627314-x\times \frac{1}{y}$$

Moltiplica 3 e 0,48480962024633706 per ottenere 1,45442886073901118.

$$0+\frac{\sqrt{3}\sqrt{3}}{2}+1,45442886073901118\times 2,062665339627314-x\times \frac{1}{y}$$

Moltiplica 1,45442886073901118 e 2,062665339627314 per ottenere 2,99999999999999987246512207937052.

$$0+\frac{\sqrt{3}\sqrt{3}}{2}+2,99999999999999987246512207937052-x\times \frac{1}{y}$$

E 0 e 2,99999999999999987246512207937052 per ottenere 2,99999999999999987246512207937052.

$$2,99999999999999987246512207937052+\frac{\sqrt{3}\sqrt{3}}{2}-x\times \frac{1}{y}$$

Moltiplica \sqrt{3} e \sqrt{3} per ottenere 3.

$$2,99999999999999987246512207937052+\frac{3}{2}-x\times \frac{1}{y}$$

E 2,99999999999999987246512207937052 e \frac{3}{2} per ottenere \frac{112499999999999996811628051984263}{25000000000000000000000000000000}.
