Step-by-step explanation:
(2 cos(2x)) / (cot x – tan x)
Multiply top and bottom by sin x cos x:
(2 cos(2x) sin x cos x) / (cos² x – sin² x)
Use double angle formula:
(2 cos(2x) sin x cos x) / (cos(2x))
2 sin x cos x
Use double angle formula:
sin(2x)
How do you want me to figure out this problem if I don’t have enough information
The equation is m-2, which is the number of magazines your friend has. Hope this helps!!!
1/5 3/5 7/10 4/5 Change the denominators all to 10 to be able to but them in order
Well, one quarter of 20 is 5 (because 20 ÷ 4 = 5). so, to find 3 quarters, we multiply 5 times 3.
5 × 3 = 15, so 3 quarters of 20 is 15.
