How do you find the sin of a log table?
Just follow these steps.
- Take Natural Sines page.
- You have 0.6667. Search for that value.
- Note the value of degrees and minutes by following the row and column. You would be in the Row of 41° and column of 48′.
- But the value you need is 0.6667 which means you have a difference of 2.
- So add.
- Thus,
What is logarithmic sine?
n. A function of an angle expressed as the ratio of two of the sides of a right triangle that contains that angle; the sine, cosine, tangent, cotangent, secant, or cosecant.
What is a sine table?
A sine table (or sine plate) is a large and wide sine bar, typically equipped with a mechanism for locking it in place after positioning, which is used to hold workpieces during operations.
How do you convert degrees to minutes and seconds?
The conversion of degrees into degree-minute-seconds can be done with the help of the conversion factor of 60. This is because: 1 degree = 60 minutes (60′) 1 minute = 60 seconds (60”)

What is the formula to find the sine of one angle?
Many angles can be computed exactly by many methods. Another practical formula is the sine of 3 times an angle: sin 9°: For example, the sine of 9 degrees is the sine of (3×3°). And so on. sin 1°: Now, to find the sine of one degree, one needs to know sine of one third of three degrees!
What is Sine in maths?
What is Sine in Mathematics? Sine, is a trigonometric function of an angle. The sine of an angle is defined in the context of a right triangle: for the specified angle, it is the ratio of the length of the side that is opposite that angle to (which divided by) the length of the longest side of the triangle (thatis called the hypotenuse).
How do you find the sine of 6 degrees?
sin 3° = sin (18° − 15°) = sin 18° cos 15° − sin 15° cos 18°. This gives us the following value of sin 3°: or other forms depending how you factor the above. sin 6°: Using the above, one can compute the sine of 6 degrees finally as sine of twice 3 degrees to arrive at.
How do you set the angle of a sine bar?
Place the spacer under one of the rolls of the sine bar or sine plate as shown in the picture. That’s it! The sine bar is now set to the desired angle.
