(csc x-1)(csc x+1)=csc²x-1²=csc²x-1=(1/sin x)² -1=1/sin x² - sin²x/sin²x=
=(1-sin²x)/sin² x = cos² x/ sin² x = (cos x/sin x)²= (cot x)²
Do 2*3 then do the answer divided by 18 to get the answrr
You would just need to make an inequality from the description. You would make "x" the number. The answer would be "x-4>-1"
