Question

if sinA/cosA equal to tanA?is cosA/sinA equal to cotA? justif?
​

Answer 1

Answer and Step-by-step explanation:

consider a right angled triangle ABC

right angled at B

such that for an angle A

base is AB and perpendicular side is BC

so sin A = (BC/AC)

cos A = (AB/AC)

tanA = BC/AB (by definition)

sinA/cosA = (BC * AC) / (AB * AC)

sinA/cosA  = (BC/AB)

tanA = 1/(cotA) = (AB/BC) (by definition)

cosA/sinA = (AB * AC) / (BC * AC)

cosA/sinA = (AB/BC)

hope this helps
