What is the golden rule for solving equations?
Do unto one side of the equation, what you do to the other! An equation is like a balance scale. If we put something on, or take something off of one side, the scale (or equation) is unbalanced. When solving math equations, we must always keep the ‘scale’ (or equation) balanced so that both sides are ALWAYS equal.
What are the 3 rules of algebra?
There are many laws which govern the order in which you perform operations in arithmetic and in algebra. The three most widely discussed are the Commutative, Associative, and Distributive Laws. Over the years, people have found that when we add or multiply, the order of the numbers will not affect the outcome.
Algebra includes both numbers and letters. Numbers are fixed, i.e. their value is known. Letters or alphabets are used to represent the unknown quantities in the algebra formula.

What are the 6 trigonometric identities?
There are six trigonometric ratios, sine, cosine, tangent, cosecant, secant and cotangent. These six trigonometric ratios are abbreviated as sin, cos, tan, csc, sec, cot. These are referred to as ratios since they can be expressed in terms of the sides of a right-angled triangle for a specific angle θ.
How do you prove an equation is an identity?
To “prove” an identity, you have to use logical steps to show that one side of the equation can be transformed into the other side of the equation. You do not plug values into the identity to “prove” anything. There are infinitely-many values you can plug in.
How do you identify an identity in math?
The easiest way to tell whether or not any equation is an identity is by graphing the difference of both sides of the equation. Use the “Graph” function on your graphing calculator. The “Y=” button opens the graphing function on most calculators. To find how to graph using your calculator, consult the owner’s manual.
Why are Trig identities so hard?
Trigonometry is hard because it deliberately makes difficult what is at heart easy. We know trig is about right triangles, and right triangles are about the Pythagorean Theorem. About the simplest math we can write is When this is the Pythagorean Theorem, we’re referring to a right isosceles triangle.
