atan(x) >= 9/5
$$\operatorname{atan}{\left(x \right)} \geq \frac{9}{5}$$
atan(x) >= 9/5
Detail solution
Given the inequality:
$$\operatorname{atan}{\left(x \right)} \geq \frac{9}{5}$$
To solve this inequality, we must first solve the corresponding equation:
$$\operatorname{atan}{\left(x \right)} = \frac{9}{5}$$
Solve:
This equation has no roots,
this inequality is executed for any x value or has no solutions
check it
subtitute random point x, for example
$$\operatorname{atan}{\left(0 \right)} \geq \frac{9}{5}$$
but
so the inequality has no solutions
$$\operatorname{atan}{\left(x \right)} \geq \frac{9}{5}$$
To solve this inequality, we must first solve the corresponding equation:
$$\operatorname{atan}{\left(x \right)} = \frac{9}{5}$$
Solve:
This equation has no roots,
this inequality is executed for any x value or has no solutions
check it
subtitute random point x, for example
x0 = 0
$$\operatorname{atan}{\left(0 \right)} \geq \frac{9}{5}$$
0 >= 9/5
but
0 < 9/5
so the inequality has no solutions
