The six basic functions of trigonometry are the sine, cosine, tangent, cosecant, secant, and cotangent functions. Abbreviated sin, cos, tan, csc, sec, cot.
tan (30 degrees) would be equal to 0.577350269.
angle can be defined as sin-1=O/H, cos-1=/H, or Tan-1=O/A
sin^2 (feta) + cos^2 (feta) = 1 sin (feta) / cos (feta) = tan (feta)

Tan(5.2 degrees) = 0.0910 Tan(5.2 radians) = -1.8856
You can use trigonometry such as cos and tan
cot(15)=1/tan(15) Let us find tan(15) tan(15)=tan(45-30) tan(a-b) = (tan(a)-tan(b))/(1+tan(a)tan(b)) tan(45-30)= (tan(45)-tan(30))/(1+tan(45)tan(30)) substitute tan(45)=1 and tan(30)=1/√3 into the equation. tan(45-30) = (1- 1/√3) / (1+1/√3) =(√3-1)/(√3+1) The exact value of cot(15) is the reciprocal of the above which is: (√3+1) /(√3-1)

tan(30)=.5773502692
Use trigonometry and the tangent ratio: tan = opp/adj and when rearranged adj (the ship's distance) = opp/tan adj = 30/tan(6) = 285.4309336 Therefore the ship is just over 285 feet from shore. Remember that the angle of depression is the same as the angle of elevation because they are alternate angles.

A useful property in Trigonometry is: tan(x) = sin(x) / cos(x) So, cos(x) tan(x) = cos(x) [ sin(x) / cos (x)] = sin(x)

A way to remember the definitions of the three most common trigonometry functions: sin, cos and tan. Used as a memory aid for the definitions of the three common trigonometry functions sine, cosine and tangent.
