How to Find the Trig Values of an Angle?

Before looking into the steps of finding a value of a trigonometric function using an angle. We will do some basic things like knowing about trigonometric values of angle.

Angle (in Degrees) 30° 45° 60° 90° 180° 270° 360°
Angle (in Radians) 0 π/6 π/4 π/3 π/2 π 3π/2
Sin 0 1/2 1/√2 √3/2 1 0 -1 0
Cos 1 √3/2 1/√2 1/2 0 -1 0 1
Tan 0 1/√3 1 √3 0 0
Cot √3 1 1/√3 0 1
Sec 1 2/√3 √2 2 -1 1
Cosec 2 √2 2/√3 1 -1

Now, look into the steps to find the value of trigonometric functions using values easily.

  • First, step write the value that was given in the problem.
  • If the angle is above 360, then divide the angle.
  • And the remainder which you get should be in the forms like (90 + θ), (90 - θ), (270 + θ), (270 - θ), (180 - θ), (180 + θ), (360 + θ), (360 - θ).
  • After that, you need to convert the trig ratios, from sin <->cos, cosec <-> sec, tan <-> cot.
  • Finally, get the answer of the trig value of an angle.

Examples:

Question 1: Find the value of CSC(-225°)?

Solution:

Given,

csc(-225°)

= csc(-180° + 45°)

= csc ( 45°)

= sec(45°)

Taking value from the table,

= √2.

Therefore, csc(-225°) =  √2.

Question 2: Find the value of sin(18π/3)?

Solution:

Given,

sin(18π/3) = sin(5π + π/3)

= sin(π/3)

= √3/2.

Therefore, sin(18π/3) = √3/2.
