Learn how to solve simplification of algebraic expressions problems step by step online. Simplify the expression (cos(x)^2-(1-sin(x)))/(cos(x)-cos(x)sin(x)). Simplify the product -(1-\sin\left(x\right)). Multiply -1 times -1. Apply the trigonometric identity: -1+\cos\left(\theta \right)^2=-\sin\left(\theta \right)^2.
Solving a math problem using different methods is important because it enhances understanding, encourages critical thinking, allows for multiple solutions, and develops problem-solving strategies. Read more
The simplification of algebraic expressions consists in rewriting a long and complex expression in an equivalent, but much simpler expression. This simplification can be accomplished through the combined use of arithmetic and algebra rules.
