Math Tutoring on Graphing Trigonometric Functions

In order to Graphing Sine functions using t-table in math tutoring, some of the characteristics of the graph are:

·       The Graph is Continuous over its Domain (-∞, ∞).

·       The Period is 2π.

·       The X-axis intercepts occur at multiplies of π and .

Some characteristics of Cosine graph are:

·       The Graph is continuous over its Domain (-∞, ∞).

·       The Period is 2π.

·       The X-axis intercepts occur at multiplies of (2n+1)(π/2) and Some characteristics of Tangent Graph are:

·       Domain {x І x≠(2n+1)(π/2) and Range (-∞, ∞).

·       The Graph is discontinuous and has Vertical Asymptotes.

·       The X-axis intercepts occur at x=nπ.

·       The Period is π and the Graph has no Amplitude.

·       The Graph is Symmetric with respect to the origin.

We can graph the basic functions like Sine & Cosine by the help of   TI84 Calculator by plotting the data.
