Graph Reciprocal Trig Functions | Trigonometry | Pre-Calculus
In this video we will explore how to graph the reciprocal function. We will do this by exploring the characteristics of cosecant, secant and cotagent to comparing them to the reciprocal functions, sine, cosine and tangent. We will then...

How to quickly find the asymptotes of any trigonometric function
π Learn the basics of graphing trigonometric functions. The graphs of trigonometric functions are cyclical graphs which repeats itself for every period. To graph the parent graph of a trigonometric function, we first identify the...

Find the domain range and period for cosecant and secant functions
π Learn the basics of graphing the secant and the cosecant graphs. Recall that the secant is the reciprocal of the cosine while the cosecant is the reciprocal of the sine. Also recall that the cosine graph is a sinusoidal graph with...

Transformations of the tangent function
π Learn how to graph a tangent function. To graph a tangent function, we first determine the period (the distance/time for a complete oscillation), the phase shift (the horizontal shift from the parent function), the vertical shift (the...

Graph the secant function with a phase shift
π Learn how to graph a secant function. To graph a secant function, we start with the cosine graph by first determining the amplitude (the maximum point on the graph), the period (the distance/time for a complete oscillation), the phase...

How to graph the cosecant graph with a phase shift
π Learn how to graph a cosecant function. To graph a cosecant function, we start with the sine graph by first determining the amplitude (the maximum point on the graph), the period (the distance/time for a complete oscillation), the...

Evaluate the limit of sinx over x
π Learn how to evaluate the limit of a function involving trigonometric expressions. The limit of a function as the input variable of the function tends to a number/value is the number/value which the function approaches at that time....
