Sine, Cosine and Tangent (often shortened to sin, cos and tan) are each a ratio of sides of a right angled triangle: To calculate them: Divide the length of one side by another side. Example: What is the sine of 35°? Using this triangle (lengths are only to one decimal place): = 0.57... = 0.82... = 0.70...
In fact Sine and Cosine are like good friends: they follow each other, exactly π /2 radians (90°) apart. The Tangent function has a completely different shape ... it goes between negative and positive Infinity, crossing through 0, and at every π radians (180°), as shown on this plot.

For an angle θ, the functions are calculated this way: Example: What is the sine of 35°? sin (35°) = Opposite / Hypotenuse = 2.8/4.9 = 0.57... Using Cartesian Coordinates we mark a point on a graph by how far along and how far up it is: The point (12,5) is 12 units along, and 5 units up.
