The minimum value of n for which tan^(-1...

The minimum value of n for which `tan^(-1)'n/pi gt (pi)/(4), n in N`, is valid is 5.

Text Solution

Verified by Experts

`:' tan^(-1)'(n)/(pi) gt (pi)/(4) rArr n/pi gt tan'(pi)/(4)`
`rArr n/pi gt 1 [:' tan'pi/4=1]`
`rArr n gt pi`
So, the minimum value of `n` is `4`. `[:' n in N` and `pi = 3.14"....".]`
