Electric Field Due to a Ring of Charge

In this video I use the double integral to solve for the moment of inertia of area of a triangle about a vertex



Ix = /

int y^2 dA

This can also be done without using double integrals if we choose a 'larger' value of...

For the graphical method:

1) Draw Geo
metry
2) Analyse the component of the system you know the most about using Va/b
= Va - Vb
3) Analyse all the components (keeping track of both magnitudes and directi
ons of...

In this online video we will learn how to find the Area of triangle in Coordinate Geometry and simple trick to remember the formula quickly.

In this video, the teacher explains how to find missing measures in triangles using congruence and similarity criteria. They cover different congruence criteria, such as side-side-side and angle-side-angle, as well as similarity criteria...

In this video, the teacher explains how to use the cosine ratio to find the length of a ladder needed to climb to a roof at a specific angle. By comparing the ratios of the side adjacent to the angle and the hypotenuse in a right...

👉 Learn how to evaluate the secant of the sum or difference of two angles using the sum/difference formulas. To do this, we first use the Pythagoras theorem to obtain all the sides of the right triangle in the unit circle. Recall that...

👉 Learn about polygons and how to classify them. A polygon is a plane shape bounded by a finite chain of straight lines. A polygon can be concave or convex and it can also be regular or irregular. A concave polygon is a polygon in which...

👉 Learn all about evaluating trigonometric functions with triangles. In this playlist, we will learn how to evaluate, sine, cosine, tangent, cotangent, secant, and cosecant when given the sides of a triangle. If we have missing sides we...

👉 Learn how to prove that two triangles are congruent. Two or more triangles are said to be congruent if they have the same shape and size. There are many postulates and theorems to determine whether two triangles are congruent. They...

In this video, students learn how to find the rules and the 9th step in a geometric triangle growth pattern using a table. The teacher explains the concept of steps and rules in patterns, and demonstrates how to identify the number of...

In this video lesson, we explain the concept of perpendicular lines and demonstrate how to identify them in different shapes. By the end of the lesson, students will be able to categorize polygons based on the number of pairs of...

👉 Learn how to apply transformations of a figure and on a plane. We will do this by sliding the figure based on the transformation vector or directions of translations. When performing a translation we are sliding a given figure up,...

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 System of Linear Equations in two Variables by Graphical Method which forms Coincident Lines (Problem Solving)

Word Problem vectors find the resultant vector

👉 Learn about dilations. Dilation is the transformation of a shape by a scale factor to produce an image that is similar to the original shape but is different in size from the original shape. A dilation that creates a larger image is...

In this lesson, students will learn how to prove the Pythagorean theorem using similarity. By investigating and following a series of steps, they will discover that by cutting a right triangle and drawing altitudes, they can create...

👉 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 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 to evaluate the integral of a function. The integral, also called antiderivative, of a function, is the reverse process of differentiation. Integral of a function can be evaluated as indefinite integral or as a definite...

👉 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...
