15tan square thita +4sec square thita=23
and we know that sec square thita=1+tan square thita
putting this value we get
19tan square thita+4=23
19tan square thita=19
then tan square thita=1
and we know that sec square thita=1+tan square thita
putting this value we get
19tan square thita+4=23
19tan square thita=19
then tan square thita=1
