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.

The sin graph is a visual representation of the sine function for a given range of angles. The horizontal axis of a trigonometric graph represents the angle, usually written as \theta , and the y -axis is the sine function of that angle. The graph does not …

The behavior of the function \(f(x) = 3\sin(2x+1)-4\) is in all ways similar to that of the function \(f(x) = \sin x\). This trigonometric function grapher will help you find the graph and the specific characteristics (period, frequency, amplitude, phase shift and vertical shift) of more complex trigonometric functions, such as \(f(x) = 3\cos ...

When hand-drawing the graphs of sine and cosine, draw vertical dotted lines at intervals to remind you of the connection to the four quadrants from the unit circle and to keep your graphs accurate. (Such dotted lines will resemble the dashed vertical grid lines in the graphs below.)

First, read the page on Sine, Cosine and Tangent. Now you will know that the sine of any angle is the length of the far side of the triangle (the "opposite") divided by the long side (the "hypotenuse"): Sine of θ = Opposite / Hypotenuse.
