1.     sec^2 θ  +  tan θ  = 0

 

Look at the graph, here : https://www.desmos.com/calculator/bpjfy9seos

 

Note that this  function is never 0....so....we have no solutions

2     sec x  =  tan x + cot x

When I did it on Desmos (https://www.desmos.com/calculator/riwpauxdrs), I got a few solutions but I don't know what they are in radian format.

If you zoom in  VERY CLOSELY  you will see that these functions ALMOST intersect....but.....apparently they don't....
