#theta=(3pi)/4#

#theta=(7pi)/4#

#4tan theta+2=2tan theta#

or

#4tantheta-2tan theta=-2#

or

#2tan theta=-2#

or

#tan theta=-1#

or

#tan theta=tan ((3pi)/4)#

or

#theta=(3pi)/4#-------------------------Ans #1#

Similarly for other values

#tan theta=-1#

or

#tan theta= tan((7pi)/4)#

or

#theta=(7pi)/4#---------------------------Ans #2#
