Assuming ya meant
to slimplify, we use a variation of the pythagorean identity and a decomposition into the sin and cos
for the pythaogreaon identity
divide both sides by
since
subsitute
recall that
also that cos(x) is an even function and thus cos(-x)=cos(x)
therfore
so we get
decompose them into
and
to get
multiply by
to get
we can furthur simlify to get
the expression simplifies to tan(x)sin(x)

Answer: 4/25</h3>
=========================================================
Explanation:
Add up the first two frequencies to get 14+18 = 32
The table shows that the person rolled either a "1" or a "2" a total of 32 times, which is the amount of rolls getting less than "3".
This is out of the 200 rolls total.
32/200 = (8*4)/(8*25) = 4/25
In decimal form, this would be 4/25 = 0.16 which is exact.
The answer is -
2x^2 + 2x + 7
Step-by-step explanation:
b=10, y= 8,A=23
Solution
10+8+23=x
41=x
X=41
