যদি cotθ = 5/12 হয়, তবে cosecθ এর মান কত?
Solution
Correct Answer: Option B
দেওয়া আছে,
cotθ = 5/12 = BC/AB
আমরা জানি,
AC2 = AB2 + BC2
⇒ AC2 = (12)2 + (5)2
⇒ AC = √169
∴ AC = 13
cosecθ = AC/AB = 13/12
cotθ = 5/12 = BC/AB
আমরা জানি,
AC2 = AB2 + BC2
⇒ AC2 = (12)2 + (5)2
⇒ AC = √169
∴ AC = 13
cosecθ = AC/AB = 13/12
