19 lut 2024 · Being familiar with the basic properties and formulas of algebra, such as the difference of squares formula, the perfect square formula, or substitution, will simplify the work involved with trigonometric expressions and equations.
The Pythagorean Theorem says that, in a right triangle, the square of a plus the square of b is equal to the square of c: a 2 + b 2 = c 2. Dividing through by c 2 gives. a 2 c 2 + b 2 c 2 = c 2 c 2. This can be simplified to: (ac) 2 + (bc) 2 = 1. a/c is Opposite / Hypotenuse, which is sin(θ) b/c is Adjacent / Hypotenuse, which is cos(θ) So (a ...
