A curve passes through the point (1, 6 ) . Let the slope of the curve at each point (x, y) be y x + ( y x ), x>0 , then, the equation of the curve is
Options
- A( y x )= (x)+ 1 2
- Bcosec ( y x )= (x)+2
- C( 2 y x )= (x)+2
- D( 2 y x )= (x)+ 1 2
Correct answer
A. ( y x )= (x)+ 1 2
Step-by-step solution
aligned & d y ~d x = y x + ( y x ) & Put y= v x & d y ~d x = v +x dv d x & v +x dv d x = v + v & v dv = 1 x ~d x aligned Integrating both sides, we get aligned & V = (x)+ c & ( y x )= (x)+ c aligned The curve passes through (1, 6 ) . ( 6 )= (1)+c c= 1 2 Equation (ii) becomes ( y x )= (x)+ 1 2
