3 dots mean the letter 'S' in Morse Code. The classic way of remebering this is the phrase "SOS" which is 3 dots followed by 3 dashes and then 3 more dots.

Find the exact value of each trigonometric function of cos pi over 3?
The exact value of (\cos\left(\frac{\pi}{3}\right)) is (\frac{1}{2}). Consequently, the values of the other trigonometric functions are as follows: (\sin\left(\frac{\pi}{3}\right) = \frac{\sqrt{3}}{2}), (\tan\left(\frac{\pi}{3}\right) = \sqrt{3}), (\sec\left(\frac{\pi}{3}\right) = 2), (\csc\left(\frac{\pi}{3}\right) = \frac{2\sqrt{3}}{3}), and (\cot\left(\frac{\pi}{3}\right) = \frac{1}{\sqrt{3}}).
What is the exact value of tan 105 degrees?
To find the exact value of tan 105°. First, of all, we note that sin 105° = cos 15°; and cos 105° = -sin 15°. Thus, tan 105° = -cot 15° = -1 / tan 15°. Using the formula tan(α - β) = (tan α - tan β) / (1 + tan α tan β); and using, also, the familiar values tan 45° = 1, and tan 30° = ½ / (½√3) = 1/√3 = ⅓√3; we have, tan 15° = (1 - ⅓√3) / (1 + ⅓√3); whence, cot 15° = (1 + ⅓√3) / (1 - ⅓√3) = (√3 + 1) / (√3 - 1) {multiplying through by √3} = (√3 + 1)2 / (√3 + 1)(√3 - 1) = (3 + 2√3 + 1) / (3 - 1) = (4 + 2√3) / 2 = 2 + √3. Therefore, tan 105° = -cot 15° = -2 - √3, which is the result we sought. We are asked the exact value of tan 105°, which we gave above. We can test the above result to 9 decimal places, say, by means of a calculator: -2 - √3 = -3.732050808; and tan 105° = -3.732050808; thus indicating that we have probably got the right result.

What do 4 dots in Morse Code mean?
Three dashes in Morse Code mean the letter O. 3 dots, followed by 3 dashes, followed by 3 dots is Morse Code for SOS.
In Morse code How many more dots than dashes are used in SOS?
Morse code for SOS is dot-dot-dot dash-dash-dash dot-dot-dot. There is a total of 6 dots and 3 dashes.
Why does Morse code use dots and dashes?
Actually Morse's original code used dots, dashes, long dashes, and very long dashes. It also used 5 different lengths of gaps. This was greatly simplified by the adoption of the International Morse Code (largely developed in Germany then modified a bit by international agreements) to just dots and dashes. The number of different length gaps was also reduced to only 3.
What different types are there of Morse code?
Three main ones:American Morse code (Morse's original, 1844)European Morse codeInternational Morse code (replaced the previous types in 1865)
How has a Morse code changed in its looks?
Morse's original code used dots, dashes, long dashes, very long dashes, and 5 different gap lengths. The International Morse Code that replaced it simplified this to just dots, dashes and 3 different gap lengths. Electromechanical and Electronic "automatic" keys that timed the dots, dashes, and gaps for the operator were eventually introduced, significantly reducing operator workload and increasing sending code speed while reducing the frequency of sending errors.
