How to Find the Exact Value of Trigonometric Functions?

Look at this trigonometric table that will be helpful in calculating the trig functions.

Trig Table

We will look into the simple step-by-step process for finding the exact value of trig functions without using the calculator.

Note down, the function that was given in the problem.
Then, simplify the given function.
Next, using the trigonometric table find the value of angles in radians or degrees.
Finally, you will get the exact value.

Example:

Question 1: Evaluate the trig function tan(π / 6)?

Solution:

Given, tan(π / 6)

Convert tan into sin and cosine,

tan(π / 6) = sin(π / 6) / cos(π / 6)

Take the values of sin(π / 6), cos(π / 6) from the trigonometric table.

tan(π / 6) = (1/2) / (√3/2)

tan(π / 6) = 1 / √3.

Therefore the value of tan(π / 6) is 1 / √3.

Question 2: Find the Exact value of sin(7π / 12)?

Solution:

Given,

sin(7π / 12)

This can be written as,

sin(π - (5π / 12))

sin(5π/12)

= 0.96.

Therefore, the exact value of sin(7π / 12) is 0.96.
