Question

1-cosA/sinA =tanA/2thenthe value of tan22*1/2is​

Answer 1

Answer:

√2-1

Step-by-step explanation:

1-Cos A/sin A = tan A/2 ---(1)

A/2 = 22*1/2

=> A = 22*1/2*2

=> A = 45

Put A = 45 in (1)

1-Cos 45/Sin 45 = tan 45/2

=>( 1- 1/√2) ÷ (1/√2) = tan 22*1/2

=> (√2-1/√2) *√2 = tan 22*1/2

=> tan 22*1/2 = √2-1
