Find the smallest positive angle θ in qi for which tan θ = 1

I believe the correct answer is 45 degrees. The smallest positive angle θ in QI for which tan θ = 1 would be 45 degrees. We obtain it as follows:

tan θ = 1
θ = tan^-1 (1)
θ = 45 degrees

Hope this answers the question. Have a nice day.

The domain is 100 becuase i said so ok. jk its 00 jk again its r jk again and again its 75jk im always kiffing okaydbdbekufir83gc84vrudnmm as 8ehehenenrn vr 0eh339520252026ee6ee8e9
