sec theta + tan theta = 2+v3......... (1)
sec^2theta- tan^2theta = 1
so, sec theta- tan theta= 1/(2+v3)= 2-v3............... (2)
on adding (1) and (2) we get
2sec theta = 4
sec theta = 2....................... [Ans]
sec^2theta- tan^2theta = 1
so, sec theta- tan theta= 1/(2+v3)= 2-v3............... (2)
on adding (1) and (2) we get
2sec theta = 4
sec theta = 2....................... [Ans]
