The derivative $\frac{d}{dx}\left(x^{\cos\left(2x\right)}\right)$ results in $\left(-2x\sin\left(2x\right)\ln\left(x\right)+\cos\left(2x\right)\right)x^{\left(\cos\left(2x\right)-1\right)}$
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
In mathematics, an equation is a statement of an equality containing one or more variables. Solving the equation consists of determining which values of the variables make the equality true. In this situation, variables are also known as unknowns and the values which satisfy the equality are known as solutions.
