Shift functions
By Khan Academy
Sal walks through several examples of how to write g(x) implicitly in terms of f(x) when g(x) is a shift or a reflection of f(x).
Find inverse values of functions
By Khan Academy
Sal explains that if f(a)=b, then f^-1(b)=a, or in other words, the inverse function of f outputs a when its input is b.
Understanding inverse trig functions
By Khan Academy
Sal is given the graph of a trigonometric function, and he discusses ways in which he can change the function to make it invertible.
Understanding inverse trig functions
By Khan Academy
Sal discusses the appropriate way to use the calculator in order to find an angle when its tangent value is given.
Find inverse values of functions
By Khan Academy
Sal is given a line segment on the coordinate plane, and he graphs the inverse of the function represented by that segment.
Understanding inverse trig functions
By Khan Academy
Sal finds the expressions that together represent all possible solutions to the equation sin(x)=1/3.
Understanding inverse trig functions
By Khan Academy
Sal find the formula for the inverse function of g(x)=tan(x-3���������������/2)+6, and then determines the domain of that inverse function.
Reciprocal trig functions
By Khan Academy
Sal finds all six trigonometric ratios (sine, cosine, tangent, secant, cosecant, and cotangent) of an angle in a given right triangle.
Shift functions
By Khan Academy
Sal graphs y=������������������x. Then, he shows a few examples of how we can shift and stretch the graphs of y=������������������x and y=x^2, and how the equations of those graphs look.
Reciprocal trig functions
By Khan Academy
Sal is given two sides in a right triangle and the cotangent of one of the angle, and he uses this information to find the missing side.
Key features of quadratic functions
By Khan Academy
Sal rewrites the equation y=-3x^2+24x-27 in vertex form (by completing the square) in order to identify the vertex of the corresponding parabola.
Comparing features of functions
By Khan Academy
Given several quadratic functions represented in different forms (as a formula, as a graph, and as a table of values), Sal finds the one with the lowest maximum value.
Comparing features of functions
By Khan Academy
Given several functions represented in different forms (as a formula, as a graph, and as a table of values), Sal finds the one with that has no x-intercepts.
Comparing features of functions
By Khan Academy
Sal is given the formula of one function and the graph of the other, and he determines which features are shared by both functions.
Symmetry and periodicity of trigonometric functions
By Khan Academy
Sal finds trigonometric identities for sine and cosine by considering angle rotations on the unit circle.
Symmetry and periodicity of trigonometric functions
By Khan Academy
Sal solves a problem by considering the periodicity of the tangent function.
Recognizing functions from tables
By Khan Academy
Sal checks whether a table of people and their heights can represent a function that assigns a height to a name.
1.3 How to find the real zeros of a polynomial function - real zeros of polynomial functions
By Mr. McLogan's Math Channel
http://www.freemathvideos.com In this video tutorial I show you how to find the real zeros of a function. I do this by substituting in zero for f(x) and solving the equation for x. There may be more than one solution for x. I show how to solve math problems online during a live classroom. This is my way of providing free tutoring for the students in my class and for students anywhere in the world. Every video is a short clip that shows exaclty how to solve math problems step by step. The problems are done in real time and in front of a regular classroom. I post all of my videos on youtube but if you are looking for other ways to interact with me and my videos you can follow me on the following pages: Tumbler: www.mrbrianmclogan.tumblr.com, Blogger: www.mrbrianmclogan.blogspot.com, Twitter: @mrbrianmclogan Facebook: mrbrianmclogan Youtube: www.youtube.com/mrbrianmclogan
Key features of quadratic functions
By Khan Academy
Sal rewrites the function f(x)=x^2-5x+6 in factored form to reveal its zeros and in vertex form to reveal its vertex.
