The value of sinxcosx is equal lớn một nửa. This value is found using the trigonometric identity sinxcosx = một nửa sin(2x), and can also be calculated using a calculator or trigonometric tables. Sinxcosx is not equal lớn cosx, as they are different trigonometric functions, although they may have the same value at certain angles. The relationship between sinxcosx and sinx is that sinxcosx equals một nửa times the sine of twice the angle, derived from the double angle identity sin(2x) = 2sinxcosx. Additionally, sinxcosx can be simplified further using other trigonometric identities, such as simplifying it lớn một nửa (1-cos(2x)) using the Pythagorean identity sin^2x + cos^2x = 1.
