Web10.5. =. 0.79. To graph the sine function, we mark the angle along the horizontal x axis, and for each angle, we put the sine of that angle on the vertical y-axis. The result, as seen above, is a smooth curve that varies from +1 to -1. Curves that follow this shape are called 'sinusoidal' after the name of the sine function. WebFor a triangle with an angle θ , the functions are calculated this way: Example: what are the sine, cosine and tangent of 30° ? A 30° triangle has a hypotenuse (the long side) of length 2, an opposite side of length 1 and an adjacent side of √3, like this: Now we know the lengths, we can calculate the functions:
