How do I plot the derivative of a function?

Already have the derivative 1- (sinx)/(squar(x))-(squar(x))(cos(x)) just don't know how to plot it via code

Answer 1

[Sulaymon Eshkabilov]

Use syms and fplot(), e.g.:

syms x
fplot()

[Batuhan Yildiz]

What is in the brackets of plot

Answer 2

[Sulaymon Eshkabilov]

To plot sin(2*x), e.g.:

syms x
fplot(x, sin(2*x), [-pi, pi]), grid on
xlabel('x'), ylabel('sin(2*x)')

Apply this exercise for your exercise.

One last thing what would happend if you had to add x=[1.0 1.5 2.0 2.5 3.0 3.5 4.0 4.5 5.0 5.5 6.0] to the codding? What would it look like?

Answer 3

[Sulaymon Eshkabilov]

It is very simple, e.g.:

x = [-3, -2.5 -2 -1 0 1 2 3];
y= sin(2*x);
plot(x, y)
