It has numerous applications in astronomy, architecture, aerospace, and defence, etc.
The trigonometry table is a useful for determining the values of trigonometric ratios for standard angles
It contains the values of trigonometric ratios those are sine, cosine, tangent, cosecant, secant, cotangent, also known as sin, cos, tan, cosec, sec and cot, respectively.
A simple method for calculating the values of sine ratios for all degrees.
To fill the cos table, just take the reverse order of sin values.
To fill tan and sec table, remember these formulas:
To fill the cot table, just take the reverse order of tan values and to fill the cosec table, just take the reverse order of sec values.
Let us learn to recall the trigonometry table using only one hand! Give each finger the typical angles as shown in the image.
We will count our fingers while filling the sine table, but for the cos table, we will just fill the data in reverse order.
Step1: Count the fingers on the left side to find the standard angle for the sine table.
Step 2: Divide the number of fingers by 4.Step 3: Take out the square root of the ratio.
