find a,b,c if f(x)= (sin(a+1)x+sinx)/x ,x<0 c ,x=0 (under root x+bx)-(under root x)/b under root x3, x>0 is constant at x=0 Share with your friends Share 46 Anuradha Sharma answered this f0-0=limh→0sina+10-h+sin0-h-h=limh→0sina+1h+sinhh=a+1h+hh=a+2 limh→0sinh=hand f0+0=limh→0h+bh2-hbh32=limh→01+bh12-1bh=limh→01+12bh+........-1bh=12which is independent of b so b may have any real value.Again by continuity at x = 0 , we have a+2=12=cSo a = -3/2 and c = 1/2. 27 View Full Answer
