What is tan11pi/6 ? Fraction

tamaranim1 [39]

11pi/6 is in 4th quadrant.

The reference angle is pi/6 because 11pi/6 is pi/6 radians away from 'x' axis.

In 4th quadrant, sin is negative and cos is positive, therefore tan is negative.

This means:
$tan(\frac{11\pi}{6}) = -tan(\frac{\pi}{6}) = -\frac{sin(\pi/6)}{cos(\pi/6)} = -\frac{\frac{1}{2}}{\frac{\sqrt{3}}{2}} = -\frac{1}{\sqrt{3}} = -\frac{\sqrt{3}}{3}$

Anya makes a scale drawing of a bug. The scale of the drawing’s length to the actual bug’s length is 2 inches: 1/8 inch. The act

<h2>Hello!</h2>

The answer is: The Anya's drawing is 6 inches long.

Have a nice day!

To solve this problem, we need to consider the drawing's length with respect to the actual bug's size, so, the scale factor is:

$2in:\frac{1}{8}in\\\\2x(in):\frac{3}{4}in$

So, how long is Anya's drawing of the bug?

We can find it, using the following equation:

$(2x)in=\frac{2in*\frac{3}{4}in}{\frac{1}{8}in}=\frac{\frac{6}{4}in}{\frac{1}{8}in}=\frac{\frac{3}{2}in }{\frac{1}{8}in}\\\\(2x)in=\frac{\frac{3}{2}in }{\frac{1}{8}in }=\frac{3}{2}in*\frac{8}{1}in=12in^{2}\\\\(2x)in=12in^{2} \\\\x=\frac{12in^{2} }{2in}=6in$

Hence, the Anya's drawing is 6 inches long.

Have a nice day!
