HELP, Prove: (cos(x))/(sin(x)tan(x))=cot^2x

Mice21 [21]

Answer:

Steps shown below

Step-by-step explanation:

We will simplify this using definitions and identities. Let's start.

$\frac{cos(x)}{sin(x)tan(x)}$

Using $tanx=\frac{sinx}{cosx}$ , we have:

$\frac{cos(x)}{sin(x)\frac{sin(x)}{cos(x)}}\\=\frac{cos^2(x)}{sin^2(x)}$

Using $cot(x)=\frac{cos(x)}{sin(x)}$ , we have:

$\frac{cos^2(x)}{sin^2(x)}\\=cot^2(x)$

Hence, proved.

Triangle RST has vertices R(−2, 2), S(1, 1), and T(−1, −3). Find the coordinates for the image of each vertex for the given rota

Vesnalui [34]

Answer:

A. $R'(-2,-2),S'(-1,1),$ and $T'(3,-1)$

Step-by-step explanation:

Given:

Vertices of triangle RST are $R(-2,2),S(1,1),$ and $T(-1,-3)$ .

Rotation is 90° about the center O(0,0). The rotation is counter-clockwise as the angle of rotation is positive.

Now, the co-ordinate rule for 90° rotation counter-clockwise is given as: $(x,y)$ → $(-y,x)$

$x$ and $y$ values interchange their places with $y$ becoming negative when interchanged.

So, $R(-2,2)$ → $R'(-2,-2)$

$S(1,1)$ → $S'(-1,1)$

$T(-1,-3)$ → $T'(-(-3),-1)$

⇒ $T(-1,-3)$ → $T'(3,-1)$

Therefore, the image of the vertices are $R'(-2,-2),S'(-1,1),$ and $T'(3,-1)$ .
