Trigonometry Examples

2

$2$

Step 1

To convert radians to degrees, multiply by

\frac{180}{π}

$\frac{180}{π}$ , since a full circle is

360 °

$360 °$ or

2 π

$2 π$ radians.

(2) \cdot \frac{180 °}{π}

$(2) \cdot \frac{180 °}{π}$

Step 2

Multiply

(2) \frac{180}{π}

$(2) \frac{180}{π}$ .

Step 2.1

Combine

2

$2$ and

\frac{180}{π}

$\frac{180}{π}$ .

\frac{2 \cdot 180}{π}

$\frac{2 \cdot 180}{π}$

Step 2.2

Multiply

2

$2$ by

180

$180$ .

\frac{360}{π}

$\frac{360}{π}$

\frac{360}{π}

$\frac{360}{π}$

Step 3

π

$π$ is approximately equal to

3.14159265

$3.14159265$ .

\frac{360}{3.14159265}

$\frac{360}{3.14159265}$

Step 4
