New ReviewIn this video I am going to work through how to evaluate a basic trig function using the unit circle and one more difficult

New ReviewWhen you are first learning how to evaluate trig functions using the unit circle there are some very important steps you need to know and understand. In this video we will dive right in

New ReviewIn this video we are going to cover the three different solutions you can expect from a system of linear equations. How to identify one solution, no solution and infinite many solutions.

New ReviewIn this video we are going to review the types of problems of trigonometry that you can expect to see on your precalculus semester 1 midterm exam

In this short math video we will use function notation to translate a function. We will understand that translating a function down impacts the y-coordinate of EVERY point on the function. We will rewrite the function by subtracting 4...

This video, entitled "Coordinates of Translations," shows how two-dimensional figures can be translated on a coordinate plane.

A video entitled "Examine Unknown Triangles" that covers how to use the distance formula and the converse of the Pythagorean theorem to see if triangles are right triangles.

This video, entitled "Translating Parallel Lines," demonstrates how a set of parallel lines can be translated on a coordinate plane.

A video entitled "Practical Examples" that covers transformations the result in similar figures, such as dilations and translations.

Pupil outcome: I can draw and complete simple shapes by plotting positions on the full coordinate grid. Key learning points: - The horizontal distance or coordinate is given first when describing positions on a coordinate grid. - If the...

Pupil outcome: I can mark the position of points specified by coordinates in the first quadrant of a coordinate grid. Key learning points: - The horizontal distance from the origin is recorded first. - Points on a coordinate grid are...

Pupil outcome: I can draw polygons specified by coordinates in the first quadrant. Key learning points: - The first digit in the coordinate gives the horizontal distance from the origin along the x-axis. - The second digit in the...

Pupil outcome: I can generate coordinate pairs for a cubic graph from its equation and then draw the graph. Key learning points: - A table of values can be useful to identify coordinate pairs which satisfy the equation. - By substituting...

Pupil outcome: I can find the inverse of a function. Key learning points: - By changing the subject, you can find the inverse function. - The inverse function maps the output to the input. - There is a graphical connection between a...

Pupil outcome: I can find the equation of a radius of a circle. Key learning points: - The equation of a circle gives the coordinates of the centre of the circle. - Using this and the coordinates of a point on the circle, you can...

In this video, we will use the equation of a circle to find the center and radius.

In this video, we do two problems graphically and algebraically involving the equations of circles.

This is my second video on deriving the Unit Circle. If you know where the angles (degrees and radians) come from, your next step is to use special right triangles to derive the points on the Unit Circle.

How do you graph y=tan(x) and y=cot(x)? Why do the graphs look the way they do? How do I know where the asymptotes and zeros are for each graph? This video answers all these questions and derives the graphs for these two periodic trig...

How do you solve trig equations that have something squared in them? In this video I show how to use a U-substitution to rewrite trigonometric equations as quadratics, which makes them easier to solve. We use the unit circle to solve...

How to write an equation in slope intercept form when given.... 1) a point and the slope 2) two points

Find all six trig ratios given a point on the terminal side of theta. In this video we work this common type of problem. We use the Pythagorean Theorem to find "r" (hypotenuse), and then use the given "x" (adjacent) and "y" (opposite) to...
