Derivatives of cos2x+1 / sin2x ?
Answers
Answer:
Since we know that,
cos2x= cos²x-sin²x=(cosx-sinx)(cosx+sinx)
And, sin2x=2sinx.cosx
Therefore,
1-sin2x= cos²x+sin²x-2sinx.cosx
1-sin2x= (cosx-sinx)²
Then let
y=cos2x/(1-sin2x)

Final answer:
The number that 21.12 constitutes 25.6% of is calculated using the formula for percentage. Rearranging the formula to find the Whole and substituting the given values in, we find that 21.12 is 25.6% of 82.5.
Explanation:
The question 21.12 is 25.6% of what number falls under the topic of Calculating Percents in Mathematics. To calculate this, use the formula for percentage which is:
(Part/Whole) = Percentage
In this case, the part is 21.12 and the percentage is 25.6%. The question is asking for the Whole number. We can rearrange the formula to find the Whole:
Whole = Part/Percentage
Substitute the given values into the formula:
Whole = 21.12/0.256 = 82.5
Therefore, 21.12 is 25.6% of 82.5.

if y varies directly as x that means
y=kx where k is a constant
so
y=kx
y=2 and 2/3 when y=1/4 then find k
convert 2 and 2/3 to imporoper fraction for ease
2 and 2/3=6/3+2/3=8/3
8/3=k(1/4)
multiply both sides by 4/1 to clear fraction
32/3=k
so now we have
y=(32/3)x
when x=1 and 1/8
find y
convert 1 and 1/8 to imporopor=9/8
y=(32/3)(9/8)
y=(288)/(24)
y=12
