Your Input

Find the reduced row echelon form of $$$\left[\begin{array}{cc}\sin{\left(x \right)} & \cos{\left(x \right)}\end{array}\right]$$$.

Solution

Divide row $$$1$$$ by $$$\sin{\left(x \right)}$$$: $$$R_{1} = \frac{R_{1}}{\sin{\left(x \right)}}$$$.

$$$\left[\begin{array}{cc}1 & \frac{1}{\tan{\left(x \right)}}\end{array}\right]$$$

Answer

The reduced row echelon form is $$$\left[\begin{array}{cc}1 & \frac{1}{\tan{\left(x \right)}}\end{array}\right]$$$A.
