Question

Find the general expression for all angles whose tangent is zero.

Solution

Let $space angle XOP equals straight x$ be any angle, then
tanx = 0
$rightwards double arrow$ $space space space space PM over OM equals 0$
$rightwards double arrow$ PM = 0
$rightwards double arrow$ OP coincides with OX and OX'
i.e. $straight x equals 0 comma space plus-or-minus straight pi comma space plus-or-minus 2 straight pi comma space..........$
So, general value of x is given by $WiredFaculty$
