Which of the following statements is true ?

Range of Values of Trigonometric Ratios

The maximum value of 1/cosec α is

Assertion: The value of sinθ + cosθ is always greater than 1. Reason: For an acute angle θ, the value of sinθ and cosθ lie between 0 and 1.

The value of sinθ + cosθ is always greater than 1.

The value of sinθ is (a + 1/a), where 'a' is a positive number.
