Sin 45 Cos 45. Sin 45 Degree Value Let us consider a rightangled triangle ABC Thus the sine of angle α is a ratio of the length of the opposite sideBC to the angle α and its hypotenuse AB Sin α = \(\frac{Opposite Side}{Hypotenuse}\) = \(\frac{Perpendicular}{Hypotenuse}\) = BC/AB So sin 45 degrees trigonometry value infraction will be sin 45° = \(\frac{Perpendicular}{Hypotenuse}\).
