Mathematics for IGCSE & O level - Pythagoras' Theorem And Trigonometry (Section 4 - No. 9)
Which of the following represents a correct application of the sine rule in triangle ABC?
a/sin A = b/cos B = c/tan C
sin A/a = sin B/b = sin C/c
a/cos A = b/sin B = c/cos C
sin A/a = cos B/b = tan C/c
Forklaring
The correct formula of the sine rule.
