dx/dt= [(3sin^2(t)cos(t)(√cos(2t))) + {(sin^3(t)(sin(2t)))/(√cos(2t))}]/cos(2t) dy/dt= [(-3cos^2(t)sin(t)(√cos(2t))) + {(cos^3(t)(sin(2t)))/(√cos(2t))}]/cos(2t) dy/dx= [{-3cos^2(t)cos(2t) + sin^2(t)sin(2t)}/{3sin(t)cos(t)cos(2t) + sin(2t)sin^2(t)}]

Ritik Yadav 7 years, 3 months ago

dy/dx= (x+2y)/(x-y) Since the degree of numerator and denominator is same,i.e. 1, then Let y=vx So dy/dx= v + x dy/dx (x+2vx)/(x-vx) = v+x dv/dx (1+2v)/(1-v) = v + x dv/dx (1+2v)/(1-v) - v = x dv/dx (1+2v-v+v^2 ) /(1-v) = x dv/dx (v^2 + v +1)/(1-v) =x dv/dx (1-v) dv/( v^2 +v+1) = dx/x So. Now you can integrate both sides and find the result...
