Verified answer
sin U / csc U + cos U / sec U = 1sin U / (1/sinU) + cos U / (1/cos U) = 1
sin² U + cos² U = 1
1 = 1 (Terbukti)
Verified answer
Materi : Identitas TrigonometriKelas : XI SMA
Sin U / csc U + cos U / sec U = 1
sin U / 1/sinU + cos U / 1/cosU = 1
sin U × sin U + cos U × cos U = 1
sin² U + cos² U = 1
1 = 1 ⇔ TERBUKTI
Identitas Trigonometri :
sin² x + cos² x = 1
