So I need help with two different types of equations the first is:
Sec^2(x)-2tan^2(x)=2/3
And I need to find all solutions in the interval [0,2pi)
If you can show me how to start solving this equation would be awesome
The second equation is:
Tan(x)=-srt3/3
I understand cos and sin but not really tan I need to find all solutions and write the equation as
X=?+pik, where k is any integer
Thanks in advance guys!!
