Just remember SOHCAHTOA,
SOH is using the sine, only use this when you have the Hypotenuse and the Opposite.
Sin(a)= O/H
CAH is using the cosine, only use this when you have the Hypotenuse and Adjasent.
Cos(a)=A/H
TOA is using the tangent, only use this when you have the Opposite and Adjasent.
Tan(a)=O/A

Is trigonometry included in order of operations?
Not specifically trigonometry, but functions in general. As a general rule, functions must be evaluated before using the results in other parts of the calcuation.
What are the 2 branches of trigonometry?
plane trigonometry spherical trigonometry
What are the kinds of trigonometry?
The main kinds are plane trigonometry and solid trigonometry. The latter will include trigonometry in hyper-spaces.
Who is the father of trigonometry?
Hipparchus is the father of trigonometry.
How do you work out the inside angle of a triangle using trigonometry?
The answer depends on what information you do have. If you have all three sides, you use the cosine rule to find any one of the angles and then use the sine rule to find the other two.
