I generally use (in order of preference):
cos(x) = 1 - 1/2! x2 + 1/4! x4 - 1/6! x6 + ... + 1/(2r)! x2r (-1)r + ...
for r = 0, 1, 2, ...
Sine and the cosine of the angle.
For a right angle triangle:- hypotenuse = adjacent/cosine or hypotenuse = opposite/sine
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.
Multiply the speed by the cosine of the angle (25 degrees in this case). For the vertical velocity, multiply by the sine of 25 degrees.Multiply the speed by the cosine of the angle (25 degrees in this case). For the vertical velocity, multiply by the sine of 25 degrees.Multiply the speed by the cosine of the angle (25 degrees in this case). For the vertical velocity, multiply by the sine of 25 degrees.Multiply the speed by the cosine of the angle (25 degrees in this case). For the vertical velocity, multiply by the sine of 25 degrees.
One is the hypotenuse times the sine of one acute angle, the other, the hypotenuse times the sine of the other acute angle (or the cosine of the first).
Sine of the angle to its cosine.
Sine and the cosine of the angle.
The sine, cosine and tangent are used to find the degrees of a right angle triangle.
For a right angle triangle:- hypotenuse = adjacent/cosine or hypotenuse = opposite/sine
at a 45 degree angle, or pi/4
All the angles in 4th quadrant have positive cosine and negative sine e.g. 280,290,300,310...etc.

Every angle has a sine and a cosine. The sine of 35 degrees is 0.57358 (rounded) The cosine of 35 degrees is 0.81915 (rounded)
Well, the easiest way to go at it is simply to remember thatthe sine and cosine of any angle are always less than 1 .
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)
