In this video, the teacher explains the concept of rational and irrational numbers, and how to identify them using examples of integers, terminating decimals, and non-terminating repeating decimals. The teacher also shows how to prove...

👉 Learn how to evaluate the six trigonometric functions given some constraints. When given the value of one trigonometric function, we can use a right triangle with one of its legs on the x-axis and the other leg, perpendicular to the...

👉 Learn how to evaluate the six trigonometric functions given a point. When given a point, there are many ways to evaluate the trigonometric functions of the point. The methods include: using the unit circle if the point is a point on...

👉 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 determine if a given SSA triangle has 1, 2 or no possible triangles. Given two adjacent side lengths and an angle opposite one of them (SSA or ASS), then there are 3 possible cases: there can be 1 solution, 2 solutions,...

Master how to determine theta in radians when given arc length and the radius

There's a thing with carbon and hydrogen in it. But how many of each?! That's the kind of thing a chemist should know. So let's do some elemental analysis!

What are Theoretical yield and losses? This is an important concept within Chemistry. In this video we will discover this answer together!

Kinetics: The Pre-Equilibrium Approximation

This video is a tutorial on balancing chemical equations. The presenter discusses the law of conservation of mass and the importance of balancing equations to determine the ratios of reactants and products. They explain the meaning of...

In this video, the teacher explains the concept of triangles and their angles, and how to identify similar triangles based on their corresponding angles and aspect ratios. The teacher also introduces the concept of scale factor and how...

👉 Learn how to write the equation of a line given points, slopes and intercepts. We will work on writing the equation of a line in slope intercept form and standard form as well as writing the equation of a line parallela and...

👉 Learn how to find the slant/oblique asymptotes of a function. A slant (oblique) asymptote usually occurs when the degree of the polynomial in the numerator is higher than the degree of the polynomial in the denominator. To find the...

👉 Learn how to evaluate an expression with the composition of a function and a function inverse. Just like every other mathematical operation, when given a composition of a trigonometric function and an inverse trigonometric function,...

Learn how an open differential works, the main parts and why we use them in this video on open differential explained

In this short math video we will answer a standardized math test question where we are given a rate and asked to find an equivalent rate. We will first identify what we are being asked to solve. Then, we will identify the rate given in...

In this short math video we will answer a standardized math test question where we are asked to identify ratios that represent a real world situation. We will identify two correct statements from a list of five. We will review how to...

👉 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 vertical/horizontal asymptotes of a function. An asymptote is a line that the graph of a function approaches but never touches. The vertical asymptote is a vertical line that the graph of a function approaches but...

This video lesson will explain the formula for slope and how to use it to find the slope using two points. Student practice is embedded and solutions are modeled. Students will be introduced to lines with a slope of zero and an...
