The following diagram shows the tangent and cotangent graphs. Scroll down the page for more examples and solutions about Tangent, Cotangent, Secant, Cosecant graphs.

Let’s practice what we learned in the above paragraphs with few of trigonometry functions graphing questions. 1) Sketch the graph of y = 5 sin 2x°  + 4 Amplitude = 5, so the distance between the max and min value is 10. Number of waves = 2 (Each wave has a period of 360° ÷ 2 = 180°)… Continue reading Graphing Trig Functions Practice

The six trigonometric functions are: Sine Cosine Tangent Cosecant Secant Cotangent Trigonometric graphs for these Trigonometry functions can be drawn if you know the following: Amplitude It is the absolute value of any number multiplied with it on the trigonometric function. The height from the centre line to the peak (or trough) is called amplitude.… Continue reading Graphs of Trigonometric Functions

The tan function is completely different from sin and cos function. The function here goes between negative and positive infinity, crossing through 0 over a period of π radian. y = tan x The tangent graph has an undefined amplitude as the curve tends to infinity It also has a period of 180°, i.e. π

y = cos x sin (x +  π/2 ) = cos x y = cos x graph is the graph we get after shifting y = sin x to  π/2 units to the left Period of the cosine function is 2π Max value of Graph Min value of the graph 1 at 0, 4π -1  at 2π There are a few… Continue reading Cos Graph

Sine, Cosine and tangent are the three important trigonometry ratios, based on which functions are defined. Below are the graphs of the three trigonometry functions sin x, cos x, and tan x. In these trigonometry graphs, x-axis values of the angles are in radians, and on the y-axis, its f(x) is taken, the value of the function… Continue reading Graphs of Trigonometric Functions
