The number of solutions of s e c x = π 4 i s Options: A . &nbsp Exactly one solution B . &nbsp Exactly two solutions C . &nbsp Infinite solutions D . &nbsp No solution

Answer: Option D : D π 4 < 4 4 π 4 < 1 B u t s e c x ≥ 1 ∀ x Hence the equation has no solutions.

The number of solutions of secx=π4 is

Question

The number of solutions of $s e c x = \frac{π}{4} i s$

Options:

A . Exactly one solution

B . Exactly two solutions

C . Infinite solutions

D . No solution

Answer: Option D
:
D

$\frac{π}{4} < \frac{4}{4} \frac{π}{4} < 1 B u t s e c x \geq 1 \forall x$

Hence the equation has no solutions.
