Question

solve abs(tanx)=1 ?
would it be tan(x)=1 tan(x)=-1
and then the pi values?

freckles · Answer

It is like solving tan^2(x)=1
which give the two equations tan(x)=1 or tan(x)=-1

freckles · Answer

And yeah |f(x)|=f(x) or -f(x)
depending our values of x in which f is positive or negative

anonymous · Answer

there is no interval asked in the question so would it be like x = 3pi/4 +-pik?

freckles · Answer

Well that is one equation...there should be another

freckles · Answer

wait that should be fine

anonymous · Answer

yeah the one for tanx = 1

anonymous · Answer

and for tanx = 1

anonymous · Answer

i meant -1

freckles · Answer

yeah we need the one for tan(x)=1 also

anonymous · Answer

then i think i got it thank you :D

freckles · Answer

I would have said x=pi/4+npi , -pi/4+npi

anonymous · Answer

well i got 3pi/4 +-pik and pi/4+-pik

freckles · Answer

same thing

freckles · Answer

my presents any integers 
(not just positive)
you don't need +/- unless you want your k's to be nonnegative integers

freckles · Answer

I was talking about my n represents any integer*

anonymous · Answer

:O i didnt know that

anonymous · Answer

ty

freckles · Answer

But you can leave it that way
It is fine
