Find the points of discontinuity, if any, of the following function: `f(x)={(sinx)/x+cosx\ \ \ ,\ \ \ if\ x!=0 5\ \ \ ,\ \ \ if\ x=0`

Explanation

When `x neq 0`, then



`f(x)=frac{sin x}{x}+cos x`




We know that `sin x` as well as the identity function `x` both are everywhere continuous. So, the quotient function



Therefore,
