![\frac{d}{dt} [3x^2-y^2]=\frac{d}{dt}[23]](/tpl/images/1043/6409/1c0bc.png)
![\Rightarrow \frac{d}{dt} [3x^2]-\frac{d}{dt}[y^2]=0](/tpl/images/1043/6409/0f010.png)
![\Rightarrow 3\times\frac{d}{dt} [x^2]-2y\frac{dy}{dt}=0](/tpl/images/1043/6409/04ddc.png)

Mary beth used the mapping rule to find the coordinates of a point that had been rotated 90° counterclockwise around the origin. examine the steps to determine whether she made an error. m (3, –6) is rotated 90° counterclockwise. (x, y) → (–y, x) 1. switch the x- and y-coordinates: (6, –3) 2. multiply the new x-coordinate by –1: (6(–1), –3) 3. simplify: (–6, –3) .
