My Math Courses
Graphing Trig Functions
This course is all about graphing the six trig functions that you will see in a trigonometry college course.
Upon completing this course, you will understand the parent graph and the standard equation of the six trigonometric functions and be able to graph each function with multiple transformations.
Inverse Trig Functions
This course is all about evaluating the six inverse trig functions in great detail, which is a topic covered in Precalculus Trigonometry at the University level.
Once you complete this course, you will understand the graphs of the six inverse trig functions. You will also be able to identify the domain and range, find the exact value and algebraically find the inverse of a trig function.
Trig Identities
This course is all about Proving/Verifying and Using Trig Identities.
Upon completing this course, you will understand how to prove the Reciprocal and Quotient Identities, Odd and Even Identities, Cofunction Identities, Pythagorean Identities, Sum and Difference Formulas, Double-Angle Identities, Power Reducing Identities, Half-Angle Identities, Product-to-Sum Formulas, and Sum-to-Product Formulas.
You will be able to use the above identities to verify other trig Identities, rewrite trig expressions, find the value of trig expressions, and solve trig equations.
