Question 244836
Well remember that {{{1^2=1}}}. So take the square root of both sides to get {{{1=sqrt(1)}}}. So taking the square root of 1 is just 1.


This gets you: {{{cot(x)=1}}}. 



{{{1/tan(x)=1}}} Now use the identity {{{cot(x)=1/tan(x)}}} 



{{{1=tan(x)}}} Multiply both sides by tan(x)



So {{{tan(x)=1}}}. Can you solve it from here? You'll need to use the unit circle if you're not familiar with all of the trig values.
