(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
Answer:
I dont know But maybe the answer is No
Step-by-step explanation:
0.3 is 30% and if 1/10 is 10% then 2/20 must be 10% because 5% is 1/20
so maybe 3/20 is only 15%
I hope this helps :)
Sorry if it dosent i suck at explaining things ; - ;
Answer:
0
Step-by-step explanation:
3x + 2 = 4
4-2 = 3x
2 = 3x
x = 2/3
2/3 x 6 = 12/3 = 4 - 4 = 0
