👉 Learn about solving logarithmic equations. Logarithmic equations are equations involving logarithms. To solve a logarithmic equation, we first use our knowledge of logarithm laws/properties to express the terms in both sides of the...

This video explains how to use estimation as a tool to get the rough value of a calculation without a calculator. The speaker provides examples of how to round values to one significant figure and perform the calculation using...

👉 Learn how to evaluate inverse trigonometric functions. When an angle is unknown but the value of one of the trigonometric functions of the angle is known, we can evaluate the value of the angle using the inverse trigonometric function...

👉 Learn about the angles 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...

SchoolOnline's Secondary Maths videos are brilliant, bite-size tutorial videos delivered by examiners. Ideal for ages 13-17, they cover every key topic and sub topic covered in GCSE Maths in clear and easy to follow...

👉 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...

Evaluate Never ending radical | Can You Solve?

👉 Learn all about sum and difference angle identities. In this video playlist, you will learn how to evaluate, solve, simplify and verify using sum and difference angle identities. We will evaluate using angles not found on the unit...

👉 Learn how to sketch angles in terms of pi. An angle is the figure formed by two rays sharing the same endpoint. Angle is measured in radians or in degrees. One complete revolution about a point is equivalent to 2pi radians and 360...

In this video, we will apply random restart as a possible solution to our local minima problem.

👉 Learn how to approximate the integral of a function using the Reimann sum approximation. Reimann sum is an approximation of the area under a curve or between two curves by dividing it into multiple simple shapes like rectangles and...

Determine Lattice Energy from Kapustinski Approximation

In this video, I explain what the Fourier series does, and why it is one of the most surprising results in mathematics. All the plotted graphs in this video were done in Mathematica. If you dont have the program then you can use the free...

In this video, well look at the fourier transform from a slightly different perspective than normal, and see how it can be used to estimate functions.

This video is a tutorial on approximation and error intervals, also known as bounds. The presenter explains how approximation is used as an estimation of the rough value of a calculation by rounding off numbers to significant figures....

Know when and how to use the “Impulse Approximation”.

👉 Learn how to classify numbers. We will classify numbers as real, imaginary, rational, and irrational.

This video focuses on logarithm in data structures.

This clip is from the chapter "Essential Concepts - I" of the series "Data Structures and Algorithms: The Complete Masterclass".This is the first part of the two-part...

An approximation is anything that is similar, but not exactly the same as something else. For example, if you were to say a 57 minute journey would take “about an hour”, you would be approximating. A value can be approximated by...

If you are wondering what Calculus is, or what youre teacher was ranting on about, this is a quick look at the basic idea behind it all.

Sep.30 -- European Central Bank President Christine Lagarde says a strategy that allows for inflation to temporarily rise above its current target could be examined as part of the institution’s wide-ranging review. "Such a strategy can...
