Finding the Exact Value Calculator

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

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.
