Question

For real raots,
[
begin{array}{l}
sec ^{2} x=0 Rightarrow sec x=0
csc x=0 Rightarrow sec x=1
1+sec x=0 Rightarrow sec x=1
end{array}
]
Thus only one rest in (0,10)

# Dolby The number of solutions of the equation tan’x – secºx + 1 = 0 in (0, 10) is - (A) 3 (B) 6 (C) 10 (D) 11 2013_ 31-320 then the least nocitive value of is sexalta
