Factor sin(x)^3-cos(x)^3
Problem
Solution
Identify the expression as a difference of cubes, which follows the algebraic pattern
a^3−b^3=(a−b)*(a^2+a*b+b^2) Assign the terms to the variables in the formula by letting
a=sin(x) andb=cos(x) Substitute these values into the difference of cubes formula to get
(sin(x)−cos(x))*(sin^2(x)+sin(x)*cos(x)+cos^2(x)) Simplify the second factor using the Pythagorean identity
sin^2(x)+cos^2(x)=1
