)
in terms of sines and cosines.
1
sin
(
720
)
Remove full rotations of
360
° until the angle is between
0
° and
360
°.
1
sin
(
0
)
The exact value of
sin
(
0
)
is
0
.
1
0
The expression contains a division by
0
The expression is undefined.
Undefined
Its 6/7 (A) because the denominators are the same, so the denominator stays the same. But if it isnt I am sorry.
From sin(a-b) = sin(a)cos(b) - cos(a)sin(b)
let a=9x, b=x
sin(9x)cos(x) - cos(9x)sin(x) = sin(9x-x) = sin(8x)
Answer:
Step-by-step explanation:
Since there are 432 tickets total and Gabriela bought 48, the chances of Gabriela not winning the grand prize is equal to the chance of any of the tickets she did not buy getting drawn. If she bought 48, then she did not buy 432-48=384 tickets. The chances of any of these being drawn is:
The GCF for 45,36,60 is 3
The LCM for 45,36,60 is 180
hope this helps
