Need code in MATLAB to plot these signals !!!

PLEASE GIVE THE CODE IN MATLAB AS SOON AS POSSIBLE !

Determine the even and odd part of the following continuous time signals and plot. (a) x(t) = e2t

(b) x(t) = sin(2t) + cos(t) + sin(t)cos(2t)

(c) x(t) = 3+2t+5t2

(d) x(t) = 10sin(t)

Determine the periodicity of the following continuous time signals and plot. (a) x(t) = 3cos(5t + /6)

(b) x(t) = cos2(2t /3)

(c) x(t) = 5cos(4t) + 3sin(8t)

(d) x(t) = 2cos(3t) + 3sin(7t)
