Solving Trigonometric Applications





 



 

My work.



 

Solving Trigonometric Equations (a third time)

A review of the compound angle formulas, the double angle formulas and the Pythagorean identity.

All the following questions required to find theta (or x or the angle) between 0 radians and 2pi radians.

First a linear example.

Solving Trigonometric Equations ( a second time)

Revisiting how to solve a trigonometric equation.

Some examples where we get a linear equation to solve:
This won starts with a reciprocal trigonometric function



 

Solving Trigonometric Equations

After the ferris wheel we formalized solving trigonometric equations. Here is the sequence of questions we worked on.

A trig function equals some number.
