Find cos(A + B) if sin A = 3/5 and sin B = 5/13 with A is quadrant II and B in quadrant I. Log in Sign up. Find A Tutor . Search For Tutors. Request A Tutor. (1 - sin 2 A) = -√(1 - 9/25) = -4/5. Since B is in Quadrant 1, cosB > 0. So, cosB = √(1 - sin 2 B) = √(1 - 25/169) = 12/13. cos(A+B) = (cosA)(cosB) - (sinA)(sinB) = (-4/5)(12/13 A× B = A B sin θ Sehingga A × B = A B sin 37° = (8)(10)(0,6) = 48 satuan.

Les sinus, cosinus et tangente n'ont pas d'unité ! Les sinus et cosinus d'un angle aigu sont compris entre 0 et 1. Par contre, la tangente peut être supérieure à 1. Jawaban Diketahui : cos a = 3/5 dan sin b = 5/13. jika a sudut lancip dan b sudut tumpul. Ditanya : tentukan nilai dari \sin (\alpha-\beta) ! sin(α−β)!

Along with the tan function, the fundamental trigonometric functions in trigonometry are sin and cos. Pourles articles homonymes, voir Borwein.. En mathématiques, une intégrale de Borwein est une intégrale mettant en jeu des produits de sinc(ax), où sinc est la fonction sinus cardinal, définie par sinc(x) = sin(x)/x.Les intégrales de Borwein, découvertes par David Borwein et Jonathan Borwein en 2001, présentent des régularités apparentes qui finissent par cesser.
