Mechanical energy problem 4 part 3

👉 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...

It explains how to find the derivatives of functions which are in parametric form.

👉 Learn how to evaluate trigonometric functions using trigonometric identities. Trigonometric identities are equalities that involve trigonometric functions. We will focus on the cofunction identities and even-odd identities. The...

👉 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,...

👉 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...

Using a toy car and a piece of paper we can visualize and understand relative motion by doing an introductory problem.

👉 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 how to find the point on the unit circle given the angle of the point. A unit circle is a circle whose radius is 1. Given an angle in radians, to find the coordinate of points on the unit circle made by the given angle with the...

This video introduces the basic definitions and terminology of differential equations. This video goes over 6 examples covering how to classify ordinary differential equations by order and linearity.

This nugget gives explanation on the resolution of vectors.

The mirror matrix (or reflection matrix) is used to calculate the reflection of a beam of light off a mirror. The incoming light beam * the mirror matrix = outgoing light beam.

How to find the minimum coefficient for an object to roll without slipping on an incline.

These second-order nonlinear differential equations can be written in the form:

dx/dt = f
(x,y)
dy/d

t = g(x,y)

Got a nonlinear differential equation? No problem, just linearize it! This method...

What is the general equation for work? Explain the concept of work in physics. Physics Work, Part 1

Cartesian and polar coordinates are introduced and how to switch from one to the other is derived. The concept of angular displacement and arc length are demonstrated. Circumference is shown to be an arc length.

U-values measure how effective a material is an insulator. The lower the U-value, the better the material is as a heat insulator. For example, a cavity wall has a u-value of 1.6, so most of the heat inside the house will stay in the...

How far does a piece of gum stuck to the outside of a 67 cm diameter wheel travel while the wheel rotates through 149°? A conversion from revolutions to degrees is performed.

This video is an educational presentation on how to calculate the area of a triangle using the formula 1:2 ab sinC. The video provides a step-by-step guide on how to use the formula, including practical examples and a proof for the...
