Sin^2(x/2)=sin^2x Find the value of x

Veronika [31]

$\sin^2\dfrac x2=\sin^2x$
$\dfrac{1-\cos x}2=1-\cos^2x$
$1-\cos x=2-2\cos^2x$
$2\cos^2x-\cos x-1=0$
$(2\cos x+1)(\cos x-1)=0$
$\implies\begin{cases}2\cos x+1=0\\\cos x-1=0\end{cases}$ $\implies\begin{cases}\cos x=-\frac12\\\cos x=1\end{cases}$

The first case occurs in $0\le x$ for $x=\dfrac{2\pi}3$ and $x=\dfrac{4\pi}3$ . Extending the domain to account for all real $x$ , we have this happening for $x=\dfrac{2\pi}3+2n\pi$ and $\dfrac{4\pi}3+2n\pi$ , where $n\in\mathbb Z$ .

The second case occurs in $0\le x$ when $x=0$ , and extending to all reals we have $x=2n\pi$ for $n\in\mathbb Z$ , i.e. any even multiple of $\pi$ .

2/5 of a bag of soil fills 1/3 of a container, Is 1 bag of soil enough to fill 1 container?

natka813 [3]

Answer:

No.

Step-by-step explanation:

Let's find out if 1 bag of soil is enough to fill 1 container.

Given:

2/5 of a bag fills 1/3s of a containter.

With the given, multiplying 2/5 by 2.5 represents one. Multiply 1/3 by 2.5 aswell.

Products:

1, and 2.5/3 or 5/6

1 bag can fill 5/6 of a container.

Therefore, 1 bag can't fill 1 container.
