Lemur [1.5K]3 years ago

Answer:

Step-by-step explanation:

cot(x)=cos(x)/sin(x)

sin(x) + cos(x) * cos(x)/sin(x) = 1/f(x)

(sin^2 + cos^(x))/sin(x) = 1 / f(x)

1 / sin(x) = 1 / f(x)

Taking the reciprocal of both sides, we get

sin(x) = f(x)

worty [1.4K]

In the given question, we have to perform this experiment and test if the inequality is true or not.

Adding the same value to both sides of the inequality will not change the inequality sign

<h3>Inequality</h3>

data;

  • 4 < 7
  • 11 > - 2
  • -4 < - 2
  • -8 < 8

In the first case, we would do follow the process

6 * 7 * 4 < 7 * 7 * 6\\168 < 294

In the second case;

11 > - 2\\\\5 + 11 > -2 + 5\\3 + 16 > 3 + 3\\4+ 19 > 6 + 4\\23 > 10

In all the scenarios, the operations did not affect the inequality sign because we are doing it equally to all side and at the end of the day nullifies each other.
