HOTs - Trigonometry- Maths . Cos 20 ° Cos 40 ° Cos 60 ° Cos 80 ° = 1/16 (Proved) in easy steps.

Use this simple cos calculator to calculate the cos value for 20° in radians / degrees. The Trignometric Table of sin, cos, tan, cosec, sec, cot is useful to learn the common angles of trigonometrical ratios from 0° to 360°. Select degrees or radians in the drop down box and calculate the exact cos 20° value easily. Cos(20) = 0.939692620786 This is the same answer you will get if you have a scientific calculator set to DEG mode and then enter 20 followed by the Cos button. To find cos of another number, please enter the number below and press "Calculate Cos". Draw a right triangle with a 20 degree acute angle and with a hypotenuse of one meter. Then take your meter stick and measure the leg next to the 20 degree angle.
