👉 Learn about the trigonometric functions using the unit circle. The trigonometric function of an angle is the value of the trigonometric functions of sine, cosine, tangent, cosecant, secant and cotangent of that angle. To use the unit...

👉 Learn how to evaluate the inverse of reciprocal trigonometric functions. Recall that the reciprocal trigonometric functions are given by the ratio of 1 and the corresponding trigonometric function. When an angle is unknown but the...

👉 Learn how to find the x and y-intercepts of a rational function. The x-intercept(s) of a function occurs when y = 0 and the y-intercept(s) of a function occurs when x = 0. To find the y-intercept of a function, we plug in zero for x...

👉 Learn how to graph a quadratic equation in vertex form by applying transformations such as horizontal/vertical shift, horizontal/vertical compression stretch and reflections. If the equation is not in vertex form, then we will apply...

👉 Learn about the points on the unit circle. A unit circle is a circle which radius is 1 and is centered at the origin in the cartesian coordinate system. To construct the unit circle we take note of the points where the unit circle...

👉 Learn all about the different trigonometric identities and how they can be used to evaluate, verify, simplify and solve trigonometric equations. The identities discussed in this playlist will involve the quotient, reciprocal,...

In this lesson, students will learn how to estimate solutions to systems of equations by graphing when both equations are in slope intercept form. They will understand the concepts of slope intercept form and how to graph linear...

In this video lesson, the teacher explains how to estimate solutions to systems of equations by graphing when both equations are in standard form. They demonstrate how to find the x and y-intercepts of each equation and graph them on a...

In this lesson, we will learn how to estimate systems of equations by graphing when one equation is in slope intercept form and the other equation is in standard form. We will review the different forms of linear equations and how to...
