Use our cos (x) calculator to find the cosine of 30 degrees - cos (30 °) - or the cosine of any angle in degrees and in radians. Since sine function is positive in the first quadrant, thus sin 30° value = 1/2 or 0. Tap for more steps Step 3. ⇒ cos 30° = cos 390° = cos 750°, and so on. Combine the numerators over the common denominator. The result can be shown in multiple forms.
For example, if we are asked to find cos 60° we can say it equals 1/2 too because 60° + 30° = 90°. Note: Since, cosine is an even function, the value of cos (-30°) = cos (30°). Since cosine function is positive in the first quadrant, thus cos 30° value = √3/2 or 0. What are the 3 types of trigonometry functions?

It uses functions such as sine, cosine, and tangent to describe the ratios of the sides of a right triangle based on its angles. Step 4.
Ptolemy's theorem states that the sum of the products of the lengths of opposite sides is equal to the product of the lengths of the diagonals. The values of sine and cosine of 30, 45, and 60 degrees are derived by analysis of the 30-60-90 and 90-45-45 triangles. These values are used very often and it is recommended from my point of view that student should be able to tell the values instantly when asked.
