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".

For real number x, the notations sin x, cos x, etc. refer to the value of the trigonometric functions evaluated at an angle of x rad. If units of degrees are intended, the degree sign must be explicitly shown (e.g., sin x°, cos x°, etc.).

Take L.H.S: cos 20° + cos 100° + cos 140°. {cos (180° - A) = - cos A}. = 2 cos 60° cos (-40°) – cos 40°. {cos (-A) = cos A}. = cos 40° – cos 40°. = 0. = R.H.S.

To obtain 20 degrees in radian multiply 20° by π / 180° = 1/9 π. Cos 20degrees = cos (1/9 × π). Our results of cos20° have been rounded to five decimal places. 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.

Notice that cos 2 (x): = (cos (x)) 2 is not the same thing as cos (2 x). It is indeed true that sin 2 ( x ) = 1 − cos 2 ( x ) and that sin 2 ( x ) = 2 1 − c o s ( 2 x ) . How do you use the half-angle identities to find all solutions on the interval [0,2pi) for the equation \displaystyle{{\sin}^{{2}}{x}}={{\cos}^{{2}}{\left(\frac{{x}}{{2}}\right)}} ?
