The sine function is symmetric about the origin, the same symmetry the cubic function has, making it an odd function. The cosine function is clearly symmetric about the y axis, the same symmetry as the quadratic function, making it an even function.
Sine and Cosine - Explained Visually
y/1 = sin Ө => y = sin Ө => the co-ordinates of p are (cos Ө , sin Ө) Remember. Sin, Cos and Tan of 0˚, 90˚, 180˚, 270˚ and 360˚. The unit circle is particularly useful when finding the sine or cosine of the angles 0˚, 90˚, 180˚, 270˚ and 360˚. The diagram below shows the values of sine and cosine of the angles mentioned above.

Finding Sin, Cos and Tan using a calculator. **Make sure your calculator is in degrees (DEG or D)** When you are given the angle put the value into your calculator and press sin, cos, or tan. Ex. Sin300 = sin900 = When you are finding the angle, put in the value you are given and press 2nd then sin, cos, or tan. Ex. Sinx = 0.3126 x =
