Answer 1

Answer:

tan(x) has infinite number of discontinuities i.e. at every

2

nπ

wheren is an integer

x[x] is discontinuous at all integers

x

∣x∣

is discontinuous where∣x∣ is discontinuous i.e. 0

sin[nπx] is also discontinuous at infinite points.

∴

x

∣x∣

is only discontinous at 0.

So the required function is

x

∣x∣
