Hi, It's Puneet

In our last class on Friday we learned some trigonometric equations.

The General Solutions of Trigonometric Equations are...

• Not bound by an interval

• Have unlimited coterminal answers

• To each solution for sinΘ or cosΘ add 360°k for degrees or 2kπ for radians

• To each solution for tanΘ add 180°k for degrees or kπ for radians

• Include with every answer: where k

• k accounts for all positive an negative coterminal integers

We learned the following equations:

secΘ=

secΘ=45°+360°

Θ = 360°-45°=315°+360°

where kEI

Θ=45°+360°k,315°+360°

Θ=π/4+2kπ,7π/4+2kπ whera kEI

tanΘ=1/√3

tanΘ=30+180k

Q4=30+180k=210+180 where kEI

[π/6+2πk] [7π/6+2πk]
