If sin = 5/12, find the exact values of cot and cos .

SashulF [63]

The exact values of the cotangent and the cosine of the angle are $\frac{\sqrt{119}}{5}$ and $\frac{\sqrt{119}}{12}$ , respectively.

According to the information given, the angle resides in the <em>first</em> quadrant of the Cartesian plane. Hence, the cosine and the cotangent of the angle are also positive.

By trigonometry we remember the concepts of sine, cotangent and cosine:

$\sin \theta = \frac{y}{r}$ (1)

$\cos \theta = \frac{x}{r}$ (2)

$\cot \theta = \frac{x}{y}$ (3)

Where $r = \sqrt{x^{2}+y^{2}}$ .

If we know that $y = 5$ and $r = 12$ , then the cotangent and the cosine of the angle are, respectively:

$x = \sqrt{r^{2}-y^{2}}$

$x = \sqrt{12^{2}-5^{2}}$

$x = \sqrt{119}$

$\cos \theta = \frac{\sqrt{119}}{12}$

$\cot \theta = \frac{\sqrt{119}}{5}$

The exact values of the cotangent and the cosine of the angle are $\frac{\sqrt{119}}{5}$ and $\frac{\sqrt{119}}{12}$ , respectively.
