...(206.) We have seen, Art. 201, that if y represents the ordinate, and x the abscissa of any curve, the tangent of the angle which the tangent line forms with the axis of abscissas, will be represented by dy_ dx If PR becomes a maximum, the tangent TP, being then parallel with the... | |

...to the circumference at the point P. Under this supposition eq. (3) becomes <4> £ in which — is the value of the tangent of the angle which the tangent line makes with axis of X. 130 By clearing this equation of fractions, and substituting for x'2+y'2 its... | |

O = slope of the indifference curve on A or B = —— It is thus clear from above that if we have to find out the MRS^ at a point on the indifference curve we can do so by drawing tangent at the point on the indifference curve and then measuring the...
