1 \div ( \cot ^{2} ( \beta )  + 1) \\  = 1  \div  \ \csc  ^{2} ( \beta )  \\  =  \sin^{2} ( \beta )

As

cosec^1/2 (B)- cot^1/2(B)=1

so cosec^1/2(B)= 1+ cot^1/2 (B)

Simplify the fraction below.<br><br> 35/4
omeli [17]

Answer:

8 3/4

Step-by-step explanation:

find the greatest common factor of 35 and 4, which is 1.  Then divide both 35 and 4 by the greatest common factor to get the following simplified fraction: 35/4

If the numerator is greater than or equal to the denominator of a fraction, then it is called an improper fraction. You could convert it into a whole number or mixed number fraction. Which would now be 8 3/4

(If its not right let me know so I can rethink my answer)
