Cos x=a maka nilai csc dan sec nya adalah?? tolong bantu gan..

- Trigonometri -

cos x = a/1
x/r = a/1

x = a, r = 1
y² = r² - x²
y² = 1² - a²
y² = 1-a²
y = √(1-a²)

csc x = 1/sin x
csc x = 1/(y/r)
csc x = r/y
csc x = 1/√(1-a²)
csc x = 1/(1-a²) √(1-a²)

sec x = 1/cos x
sec x = 1/a

semoga membantu
