Sum no. 25 tangent and normal sum Share with your friends Share 0 Saksham Tolani answered this Dear Student, First curve is given by, y=x2-3x+1 ---(1) Differentiate w.r.t. x, we get, dydx=2x−3 Thus, slope of tangent to this curve is, m1=2x−3 Second curve is given by, x(y+3)=4 ∴x(y+3)=4 ---(2) Differentiate w.r.t. x, we get, dydx=-4x2 Thus, slope of tangent to this curve is, m2=-4x2Now, given to check for point (2,-1)[m1](2,-1)=2(2)-3=1[m2](2,-1)=-422=-1Now, m1×m2=-1Thus, curves intersect each other at right angle Regards! 0 View Full Answer
