Trigonometry – Sum and Difference of Angles Identities

Trigonometry – Sum and Difference of Angles Identities

In this “State of the Triangle” teaching address, President ObaMATH explores how to apply sum and difference identities with trigonometry. Trig sum and difference formulas help us evaluate sin, cos, tan, csc, sec, and cot of non special right triangle angles, like sin 15°, for example. Um, get ready to sing with us, seriously? Seriously.…

Solving Trigonometric Equations By Factoring & By Using Double Angle Identities

Solving Trigonometric Equations By Factoring & By Using Double Angle Identities

This trigonometry video tutorial explains how to solve trigonometric equations by factoring and by using double angle formulas and identities. It explains how to factor trigonometric expressions using the difference of perfect squares method and the same techniques used to factor trinomials in algebra.

Cyclic Groups  (Abstract Algebra)

Cyclic Groups (Abstract Algebra)

Cyclic groups are the building blocks of abelian groups. There are finite and infinite cyclic groups. In this video we will define cyclic groups, give a list of all cyclic groups, talk about the name “cyclic,” and see why they are so essential in abstract algebra. If​ ​you​’d​ ​like​ ​to​ ​help​ ​us​ ​make​ ​videos more…

Difference Quotient – What is it? (PreCalculus)

Difference Quotient – What is it? (PreCalculus)

How to find the Difference Quotient. We discuss how the difference quotient represents a formula for the slope between points but as the distance between the two points decreases you get the instant rate of change or the slope of the tangent line. 0:04 What is the Difference Quotient 0:11 Formula for the Difference Quotient…

Trigonometry CAST diagrams and equations

Trigonometry CAST diagrams and equations

Trigonometry at AS/A Level includes solving trigonometric equations, and finding multiple solutions using a CAST diagram (or graph). In this video I introduce the CAST diagram and how to use it so solve equations. This is a notoriously difficult topic to teach so I’ve done my best – hope it makes sense! What’s included: -Solving…
