Evaluated at z = 1/2 and squared, the equation Γ(1/2)² = π reduces to the Wallis product formula. The gamma function is also connected to the Riemann zeta function and identities for the functional determinant, in which the constant π plays an important role. The gamma function is...

This is because in trigonometric functions, the range of sin and cos is [-1,1], so their squared values are all within [0,1]. After taking the square root, we take the non-negative value. 希望这个解答能够帮助您更好地理解sin和cos之间的相互转化关系。如果您有任何疑问或需要进一步的解释,...
