Question

The radius of curvature of the curve y=4 sinx at x=π/2 is ____

1/2

1/4

0

Option 4

​

Answer 1

Answer:

y = 4

Step-by-step explanation:

Given: Radius of curvature = 4sinx , x = $\pi$/2  

                                             = 4 (sin90°)      { $\pi$ = 180°}

                                             = 4(1)
