The area (in sq units) of the triangle formed by the normal drawn at the point (1,0) on the curve x = e ^ y with the coordinate axes is
Options
- A1
- B1 4
- C1 2
- D3 8
Correct answer
C. 1 2
Step-by-step solution
x=e^ y x= y 1 x = y d y d x d y d x = 1 x y Slope of normal at (1,0)=- 1 ( d y d x )_ (1,0) =- .x y |_ (1,0) m=-1 0=-1 Equation of normal to curve at (1,0) : (y-0)=m(x-1) y=-(x-1) x+y=1 OBA is the required region, whose area we have to calculate Area = 1 2 OB OA = 1 2 1 1= 1 2 ( . unit .^2 )
