is there supposed to be a picture? maybe i will be able to help u then
There would be 2 raised to c elements in the power set. Elements of the
power set are formed by making a binary decision on each element of the input
set: include or do not include. Since there are two choices for each element of
the input set, and there are c elements in the input set, there are 2^c possible
arrangements of these input elements.
They are not because 1/2 you cannot multiply it by anything to get 1/8
Answer: the answer is c- 16
The following expressions (1+cosβ)(1−cosβ)sinβ is equivalent to sin³β
<h3>What are Trigonometric Ratios ?</h3>
In a Right angled triangle , trigonometric ratios can be used to determine the value of angles and sides of the triangle.
The trigonometric expression given in the question is
(1+cosβ)(1−cosβ)sinβ
(a+b)(a-b) = a² - b²
( 1 - cos²β)sinβ
By the trigonometric Identity
1-cos²β = sin² β
sin² β x sin β
sin³β
Therefore Option B is the correct answer.
