Question

What is the solution to the trigonometric inequality 2-3cscx) > 8 over the interval 0 5x52x radians

Answer 1

Answer:

The solution to the inequality is

x > 2π

Step-by-step explanation:

Given the inequality :

2 - 3cscx > 8

We want to find the solution to this.

2 - 3cscx > 8

-3cscx > 8 - 2

-3cscx > 6

cscx < -2

But cscx = 1/cosx

1/cosx < -2

cosx > -1/2

x > arccos(-1/2)

x > 2π
