# Cotangent

If the angle α is acute, and cotan α = 1/3. Determine the value of sin α, cos α, tg α.

sin α =  0.95
cos α =  0.32
tg α =  3

### Step-by-step explanation:

$\mathrm{cos}\alpha =\frac{1}{\sqrt{{1}^{2}+{3}^{2}}}=0.32$ Did you find an error or inaccuracy? Feel free to write us. Thank you! Tips to related online calculators
