How to find the table of values of sin and cosine?
Not too sure what you are asking. For sinx, if x = 0, then sin0 = 0. sin 90 deg = 1, sin 180 deg = 0, sin 270 deg = -1, and sin 360 deg = 0. Some in between points are sin 30 deg = 1/2; sin 60 deg = sqrt 3/2, etc. sin 3x = 0 when x = 0 sin ... Read More »

How to find the exact angle using natural cosines table.?
You cannot find the exact value, it is irrational. One very rarely uses tables for finding angles or trig values since calculators are quicker and much more accurate. Mine gives 79.02387134 degrees. This is not exact! Read More »

Use a Taylor series to expand about an angle that you know the answer for, e.g, for your example choose theta = π/3 = 60°, for which you know sin(π/3) = √3/2 sin(x + π/3) = √3/2 + x/2 - √3*x^2 /4 - ... for theta = 61° x = (1/180) x π = 0.01...
