Question

secx=1/2 is it true or false​

Answer 1

Answer:

False

Step-by-step explanation:

Note that sec(x) = $\frac{1}{cos(x)}$

sec(x) = $\frac{1}{2}$

⇒ cos(x) = 2

We know that the range of the function f(x) = cos(x) is [-1,1] only, Hence there is no real value for x for cos(x) to be 2. Hence the answer is false.
