If `(tan(I n6)dottan(I n2)dot"tan"(I n3))/(tan(I n6)-tan(I n2)-"tan"(I n3))=k ,` then the value of `k` is________

Text Solution

Verified by Experts

The correct Answer is:
1
In 6 = In 3 + In 2
If `gamma = alpha + beta`, then
`tan gamma - tan alpha - tan beta= tan gamma * tan alpha * tan beta`
`rArr = ( tan ("In 6")* tan ("In 2")* tan ("In 3"))/( tan ("In 6")- tan("In 2")- tan("In 3")) =1`
