How do you solve: xtanx-1=0 [0,2π]

OpenStudy (anonymous):

Are you allowed to use a graphing calculator for this?

OpenStudy (anonymous):

yes!!!!

OpenStudy (anonymous):

I don't see an easy way to solve that...so graph y = xtanx - 1 and see where it intersect the x-axis between 0 and 2pi. That will be where it equals 0.

oh okay. thank you =)
