Question

The value of 3 seca - CosecA, if tanA= 1/3
and π<A<3π/2 is​

Answer 1

Answer :

tanA=1/3=opposite/adjacent

AC²=AB²+BC²

AC²=(1)²+(3)²

AC²=1+9

AC²=10

AC=Root 10

SecA=Hypothenes/Adjacent =root 10/3

CosecA=Hypothenes/opposite =root 10/1=root 10

3secA-CosecA=3×root 10/3 - root 10

=root 10 - root 10

=0
