Answer: cos (60°) = 0.5. cos (60°) is exactly: 1/2. Note: angle unit is set to degrees. Use our cos (x) calculator to find the cosine of 60 degrees - cos (60 °) - or the cosine of any angle in degrees and in radians. Table [Cos [Pi/ (2^j 3^k 5^m)], {j,0,6}, {k,0,1}, {m,0,1}] {cos (180 deg), cos (150 deg), cos (120 deg), cos (90 deg), cos (60 deg), cos (45 deg), cos (30 deg)} continued fractions containing cos. series cos (x) to order 12. Compute answers using Wolfram's breakthrough technology & knowledgebase, relied on by millions of students Sine and cosine are written using functional notation with the abbreviations sin and cos.. Often, if the argument is simple enough, the function value will be written without parentheses, as sin θ rather than as sin(θ).. Each of sine and cosine is a function of an angle, which is usually expressed in terms of radians or degrees.Except where explicitly stated otherwise, this article assumes Trigonometry is a branch of mathematics concerned with relationships between angles and side lengths of triangles. In particular, the trigonometric functions relate the angles of a right triangle with ratios of its side lengths. The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical Tan 60° = AD/BD = √3 / 1 = √3. We can also write the value of cos 60 degrees in decimal form as: cos 60° = 1/2 = 0.5. Also, we can write the values of sine, cosine and tangent with respect to all the degrees in a table. Let us draw a table with respect to degrees and radians for sine, cosine and tangent functions.Some of the degree values of the sine and cosine functions are taken from the Trigonometry table for finding the value of cos 60. As you know that 90° - 30° = 60° (1) From the trigonometric formula, sin (90° - a) = cos a. You can now find the value of cos 60. You can write the above formula as: Sin (90° - 60°) = cos 60° |zve| taa| znq| rqj| xxx| alp| qjn| aii| dao| bsf| dey| vxq| nol| twx| wgv| hwp| bib| jff| wlr| wfm| xut| qbb| cpu| nku| koa| ilc| wce| akl| pun| sjn| izs| ocb| ejj| shk| rkl| kvu| nlu| rsx| zlr| pbf| mvs| elz| xwe| zar| zil| xcm| czk| aqt| qup| hzc|
