Learn how to sketch the graph of a hyperbola in general form

Given foci and vertices, write the equation of a hyperbola

Find the foci, vertices and asymptotes of a hyperbola then graph

👉 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 graph a hyperbola given the vertices and foci

Subtract two rational expressions

All PCs make heat. Too much heat will damage components, so the heat must be dissipated from the system. Cooling fans, fins and liquid cooling can make a system cooler. This clip is from the chapter "Power Supplies" of the series...

Geeks go into PC cases and this episode is a case in point, if you’ll pardon the pun. Mike explores inside, pointing out the typical components you’ll find. This clip is from the chapter "The Visible Computer" of the series "CompTIA A+...

👉 Learn about angles in trigonometry. An angle is the figure formed by two rays sharing the same endpoint. The two rays are called the sides of the angle while the common endpoint of the two rays is called the vertex of the angle. Angle...

Gamers beware: sometimes your favourite game can get you arrested. From Saints Row 4, to Mass Effect, to The Sims, here are 10 Banned Video Games.

👉 Learn the basics of graphing a tangent and a cotangent function. To plot the tangent and the cotangent graph we choose a set of points and form a table of values with which we plot the points on the x-y coordinate axis to obtain the...

👉 Learn how to evaluate the limit of a function from the graph of the function. The limit of a function as the input variable of the function tends to a number/value is the number/value which the function approaches at that time. When...

👉 Learn how to evaluate the cosine of an angle in radians using the sum/difference formulas. To do this, we first express the given angle as a sum or a difference of two (easy to evaluate) angles, then we use the unit circle and the...

It was pretty basic – but also revolutionary! Find out how American physicist William Higinbotham created Tennis For Two and discover its links to the mysterious Manhattan Project.
