cos = adjacent / hypotenuse
mathematical equation
6
The cosine function is mathematical equation to determine the adjacent angle of a triangle. The cosine of an angle is the ratio of the length of the hypotenuse: so called because it is the sine of the co-angle.
For finding the angles in a right angled triangle the ratios are: sine = opposite divided by the hypotenuse cosine = adjacent divided by the hypotenuse tangent = opposite divided by the adjacent
Inverse of Cosine is 'ArcCos' or Cos^(-1) The reciprocal of Cosine is !/ Cosine = Secant.

Sine allows us to find out what a third side or an angle is using the equation sin(x) = opposite over hypotenuse (x being the angle). Cosine has the same function but instead uses the equation cosine(x)= opposite over adjacent
9C = 5(F - 32) is one possible answer.
It is cosine*cosine*cosine.

A simple wave function can be expressed as a trigonometric function of either sine or cosine. lamba = A sine(a+bt) or lamba = A cosine(a+bt) where lamba = the y value of the wave A= magnitude of the wave a= phase angle b= frequency. the derivative of sine is cosine and the derivative of cosine is -sine so the derivative of a sine wave function would be y'=Ab cosine(a+bt) """"""""""""""""""" cosine wave function would be y' =-Ab sine(a+bt)
To find the phase constant in a given wave equation, you can use the formula: phase constant arctan (B/A), where A and B are the coefficients of the sine and cosine terms in the equation. This will give you the angle at which the wave starts in its cycle.
Simple harmonic motion (SHM( is defined by the second order differential equation: d2y/dt2 = -ky where y is a fubction of time, t and is the displacement (relative to the central position), and k is a positive constant. The equation says is that at any given position of the object undergoing SHM, its acceleration is proportional to its displacement from, and directed towards the central position. The sine and cosine functions are solutions to the differential equation.
Cosine of 1 degree is about 0.999848. Cosine of 1 radian is about 0.540302.
