How to Graph the Cosecant Function
Description
A detailed tutorial on solving the graph of the cosecant function. Step by step tutorial including several examples of how to solve the graph of the cosecant function for reference.
Overview
The graph of cosecant is very closely related to the graph of secant. The graph appears to be many concave up and concave down curves placed in periods of 2pi. In reality, the local maximums and minimums on the graph of cosecant match up with the local maximums and minimums on the graph of sine, making it easy to line them up together. This is because sine and cosecant are the opposite of each other – sine is equal to one over cosecant.

How to Graph the Secant Function

Identifying the Cofunction
Description
A detailed tutorial on identifying the cofunction. Step by step tutorial including several examples of how to identify the cofunction for reference.
Overview
In math, we say that a function f is a cofunction of a function g if f(A) = g(B), and A and B are complimentary angles. Cofunctions are very often used with trigonometric functions like sine, cosine, and tangent. If you write a function in terms of its cofunction, it can make it easier to solve certain equations.

How to Solve Derivatives with Trigonometric Functions
Description
This video shows the basic trigonometric functions and their derivatives. Content is laid out in an organized and easy to follow manner.
Overview
Trigonometric functions, also known as just trig functions, are very common – they are sine, cosine, tangent, secant, cotangent, cosecant. These are derivatives that you should have memorized, because there is no good way to solve for them.
d/dx sin(x) = cos(x)
d/dx cos(x) = -sin(x)
d/dx tan(x) = sec^2(x)
d/dx sec(x) = sec(x) * tan(x)
d/dx csc(x) = -csc(x) * cot(x)
d/dx cot(x) = -csc^2(x)
