Convert cosine to sine
With this online calculator you can convert sin to cos (sine to cosine) and vice versa.
Formula:
sin2(x) + cos2(x) = 1
Value sine and cosine:
sin (x) = -1 ... +1
cos (x) = -1 ... +1
The sine and cosine is a trigonometric function of an angle. More generally, the definition of sine (cosine) can be extended to any real value in terms of the length of a certain line segment in a unit circle. The sine or cosine function is commonly used to model periodic phenomena.
