Question

What happens to Sec x when x increases from 0 degrees to 90 degrees?

Answer 1

Answer:

sec x =1÷cosx hence when x increases from 0 to 90 then sec x will increase but at 90 it will tends to infinity

Answer 2

Value of sex x increases when x changes from 0° to 90°.

Step-by-step explanation:

Function is = sec x

Value of x increases from 0 to 90 °

Put x = 0°

⇒ sec 0° = 1

Put x = 30°

⇒ sec 30° = 1.15

Put x = 45°

⇒ sec 45° =1.414

Put x = 60°

⇒ sec 60° = 2

Put x = 90°

⇒ sec 90° = infinity

We see that value of sex x increases when x changes from 0° to 90°.
