The inverse trigonometric functions
Learn about the inverse functions of sine, cosine, and tangent, and how they are defined even though the functions are not really invertible. These functions will be very helpful when you will solve trigonometric equations.
Sal introduces arcsine, which is the inverse function of sine, and discusses its principal range.
Sal introduces arctangent, which is the inverse function of tangent, and discusses its principal range.
Sal introduces arccosine, which is the inverse function of cosine, and discusses its principal range.
Given a sine, cosine, or tangent value, find the principle angle who has this value. In other words, find the arcsine, arccosine, or arctangent of that value.
Sal is given the graph of a trigonometric function, and he discusses ways in which he can change the function to make it invertible.
Sal find the formula for the inverse function of g(x)=tan(x-3π/2)+6, and then determines the domain of that inverse function.
Sal discusses the appropriate way to use the calculator in order to find an angle when its tangent value is given.
