What is the circumference of a round pizza with an area of 36 square inches?

1 answer:

8 0

Knowing that your area is: $A= \pi r^{2}=36 in^{2}$ you can find the radius as:
$r= \sqrt{ \frac{36}{ \pi } } =3.4 in$ ;
With this you can evaluate the circumference as:
$C=2 \pi r=2*3.14*3.4=21.3 in$

Verify the following trigonometric identity: (csc x + cot x)^2 = cos x +1/ 1- cos x

Airida [17]

9514 1404 393

Explanation:

As written, the equation is not an identity. Perhaps you want to show ...

(csc(x) +cot(x))² = (cos(x) +1)/(1 -cos(x))

We will transform the left-side expression to the form of the right-side expression.

$(\csc(x)+\cot(x))^2=\left(\dfrac{1}{\sin(x)}+\dfrac{\cos(x)}{\sin(x)}\right)^2=\dfrac{(1+\cos(x))^2}{\sin(x)^2}\\\\=\dfrac{(1+\cos(x))^2}{1-\cos(x)^2}=\dfrac{1+\cos(x)}{1-\cos(x)}\cdot\dfrac{1+\cos(x)}{1+\cos(x)}=\boxed{\dfrac{\cos(x)+1}{1-\cos(x)}}$
