limx04+sinx2x
a. It can be written as,
limx04+sinx2x=limx04+sinx4sin0x0
Now comparing with limxag(x)g(a)xa, we get
g(x)=4+sinx and a=0
b. Differentiating g(x)=4+sinx with respect to x, we get
g(x)=124+sinxd(4+sinx)dx
=124sinx(0+cosx)
=cosx24+sinx
Therefore,
limx04+sinx2x=limx04+sinx4+sin0x0
=g(0)
=cos0{24+sin0}
=14
By using calculator, we get
limx04+sinx2x=14
