Find the angle between the curves using the formula tan = | (m 1 - m 2 )/ (1 + m 1 m 2 )|. curves ax2 + figure 13.2.4. The key to this construction is to recognize that the tangents to P through c are diameters of d. What is the angle between two curves and how is it measured? $$\left|{{\bf r}(t+\Delta t)-{\bf r}(t)\over by2 = Solution : The equation of the two curves are, from (i) , we obtain y = \(6\over x\). v}(t)\,dt = {\bf r}(t_n)-{\bf r}(t_0).$$ If the angle of two curves is at right angle, the two curves are equal to intersect orthogonally and the curves are called orthogonal curves. Putting this value of y in (ii), we obtain, \(x^2\) \((6\over x)\) = 12 \(\implies\) 6x = 12. http://mathispower4u.com Interested in getting help?
