Question

if A is an acute angle sin A = 3/5,find all other trigonometric ratio of an angle A

Answer 1

cos a =4/5
tan a=3/4
cosec a =5/4
sec a=4/3
cot a =4/3

Answer 2

Given sinA= 3/5 = P/H

By Pythagorus theorem
Base =4cm

So cosA= B/H
= 4/5 Ans
SecA= 5/4 Ans

TanA= sinA/cosa

= 3/5/4/5
= 3/4Ans

CotA= 4/3Ans

CosecA= 5/3 Ans
