Fancy Trig Equations

Find out how to convert fractions of a degree with Degrees, minutes and seconds, and enter the wonderful world of the radian. I have a some examples of how to convert from degrees to radians and back again, as well as angular and linear speed using radians: Video Link

Video at Archive.org Video at YouTube Solving for an unknown in the exponent requires logarithms! 19 Problems are explained that involve graphing and the properties of exponents and logarithms, as well using your graphing calculator

Matrix Determinant Video Use Cramer's Rule to solve a system of equations with Leinitz and Sarrus' method of finding the determinate of a matrix!

To solve for an unknown angle we will use all sorts of clever tricks, employing the trig formulas and identities in weird and wonderful ways!

Proof of the sum and difference formulas for sine, cosine and tangent

Using the trig identities for substituting a Pythagorean looking expression.

An Arithmetic Sequence is a pattern where each element changes by adding a constant. Here are examples, as well as the proof the formula for a partial sum of an arithmetic sequence.

Here we find the trig functions of other angles based on the sum and difference of two angles, the double or half angle. We will prove these formulas in a different video

Here we use the trigonometry from our first Trig Chapter (4 in our textbook) to review how sine, cosine and tangent are used to solve word problems

Use the inverse trig functions to find unknown angles and use everything you know about sine cosine and tangent to solve word problems
