Question

if tan A +1/tan=2 , find tan^2A+1/tan^2 A=?​

Answer 1

Answer:

a

Step-by-step explanation:

a=a

Answer 2

Step-by-step explanation:

tanA=1/cotA

so, tanA+cotA=2...(1)

when A=45°

the eqn is satisfied as cot45 =tan45 =1

A=45°

now putting value of A in

=tan^2(45°)/1+tan^2(45°)

formula sin2A =tan^2(A)/1+tan^2(A)

=sin2(45°)

=sin90°

=1
