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.
Measure it or use trigonometry if the 'included' angle is given.
Because if you did operations in an impermissible order, or violated laws of operations, then your solution to the equation is wrong.

Because if you perform the operations in a different order your answer will be wrong.
The main kinds are plane trigonometry and solid trigonometry. The latter will include trigonometry in hyper-spaces.
Measure it or use trigonometry if the 'included' angle is given.
If you put in parentheses, you can change the order of operations in many cases, as parentheses come before everything in the order of operations.
It means that the calculator can follow the order of operations and do the order of operations for you but, you need to know how to do them on your own too.

We have to use the order of operations so everyone solves a problem the same.

Math! More specifically, depending on the level, you might study basic operations (addition, subtraction, multiplication, division) with integers; basic operations with decimals; basic operations with fractions; basic operations with negative numbers; percentages; ratio and proportion; algebra; calculus; trigonometry; and many others more.
