(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
Nothing is mentioned...how am I supposed to help you?
The formula for finding the area of a parallelogram is-
A=b*h Where A=Area b=base length h=height
A=10*4
A=40
Answer:
y= 
Step-by-step explanation:
2x+3y=C
isolate y
3y=C-2x
y=
Answer:
There is a 1/6 chance of rolling a certain number and 1/2 chance of getting a heads.
1/6 x 1/2 = 1/12 so C.
1 is the chance of getting the wanted number / 6 is all the numbers in total
When there are multiple chances you just multiply the fractions
