How to plot both functions in one plot?

f = inline('sin(x/2)')
g = @(y) 2*cos(y)

[Rik]

My two questions are:

1. Why are you using an inline function?
2. What have you tried yourself?

[Shraddha Pandey]

f = inline('sin(x/2)')
g = @(y) 2*cos(y) 
x = 0:0.1:2*pi
y1 = sin(x/2)
y2 = 2*(cos(x))
[AX,L1,L2] = plotyy(x,y1,x,y2)

[Walter Roberson]

your f and g assignment are not being used.

syms x y
fplot(sin(x/2))
hold on
fplot(2*cos(y))
help fplot

[Shraddha Pandey]

what is syms

Looks like you solved the problem by your comment above? Did you read the documentation of fplot?? It belongs to symbolic math toolbox used to define variables symbolically.
