If tan A = (1-cos B)//sinB, then tan 2A...

If tan A = `(1-cos B)//sinB`, then tan 2A = tan B.

Text Solution

Verified by Experts

The correct Answer is:
True
Since, `tanA = (1-cosB)/(sinB) = (2sin^(2).(B)/(2))/(2sin.(B)/(2)cos.(B)/(2))`
`tanA = tan B//2`
`implies tan 2A = tan B`
Hence, it is a true statement.
