    A derivative is the slope of the tangent line to the graph of a function at a value of x or the instantaneous rate of change of y with respect to x

    if function is y = x^2 the slope of its tangent at pt (x,y) is 2x as dy/dx = 2x, dy/dx is the derivative of y wrt x...

    see actually derivative means the ratio of change in dependent variable to change in independent variable...dy/dx

    Slope of tangent to curve y = 3x^2 at (1,3) dy/dx = 6x slope = dy/dx = 6(1) = 6
