?
θ is the positive acute angle and sinθ - cosθ = 0, then the value of secθ + cosecθ is?
Answer & Solution
Correct Answer:
Option
C
$$\eqalign{
& \sin \theta - \cos \theta = 0 \cr
& \sin \theta = \cos \theta \cr
& \theta = {45^ \circ } \cr
& {\text{Then,}} \cr
& sec\theta + {\text{cosec}}\theta \cr
& = \sqrt 2 + \sqrt 2 \cr
& = 2\sqrt 2 \cr} $$
