|x+2|*3-x/-x-1<=0
(x^2-7|x|+10)/(x^2-6x+9)>=0
(1/2)^(2x+1)<4
5x^2-2x^4+7>0
Derivative of:
cos(x/2)
Graphing y =:
cos(x/2)
Limit of the function:

co sinus of e of (x divide by 2) less than or equal to square root of minus 3 divide by 2
co sinus of e of (x divide by two) less than or equal to square root of minus three divide by two
cos(x/2)<=√-3/2
cosx/2<=sqrt-3/2
cos(x divide by 2)<=sqrt-3 divide by 2
Similar expressions
cos((x/2)+(pi/6))>=1/2
cos(x)/2<0
cos(x/2)<=sqrt+3/2

$$\cos{\left(\frac{x}{2} \right)} \leq \sqrt{x} - \frac{3}{2}$$

cos(x/2) <= sqrt(x) - 3/2
