Find the value of Integral sin60°.dx(Step by step) |
|
Answer» Step-by-step explanation: Let ABC be an EQUILATERAL triangle. Draw AD perpendicular to BC. Then 'D' is the middle point of BC. Let each SIDE of equilateral triangle be 2a.Then BD=a=CD. And AD=underrootABsquare - BDsquare =UNDERROOT 4asquare-a square =a underroot 3 Sin60°=AD/AB =a underroot 3/2a =underroot3/2 |
