Basicially justifying is when you use altenative formulas in order to prove your general rule works.

If the question is about...	Your Primary Method	Your Justification Method (Alternative)
Solving for x	Isolating the variable	Substitution: Plug the answer back in.
Right Triangles	Trigonometry (sin cos tan)	Pythagorean Theorem: a^2 + b^2 = c^2.
Area/Volume	Standard Formula	Break the shape into smaller squares/triangles.
Sequences	Finding the general rule (nth term)	- Use other sequence within the question (e.g the perimeter sequence) and this is usually given, and derive IT'S general rule into an equation to prove your area formula for example

These are just my suggestions on what i would do to approach the question

we worked our asses off, lets hop the exam flies by tmrw
