Question

plz explain briefly ​

Answer 1

Explanation:

a.

sinωt + cosωt

= √2 { 1/√2 sinωt + 1/√2cosωt}

= √2{cos45°. sinωt + sin45°.cosωt}

= √2sin(ωt + 45°)

This is in the form of y = Asin(ωt ± θ)

• This is a periodic function.

(b)

log ωt

It also increases monotonically with the time. It does not repeat itself.

• This is a non- periodic function.
