How to enter the following functions

Hello,

So I need to enter the functions

6cos(theta)=theta/5 in the interval [pi,2pi] and

e^(-0.01x)=7x-2 in the interval [0,3]

The objective is to use the fzero opperator and stuff.

How can I do this?

you need to rewrite so that the given equations are equal to zero. Then fzero finds x.

fun = @(x) something with x equal to zero
x0 = some starting point
res = fzero(fun,x0)

In particular, the form

first_expression_in_variable = second_expression_in_variable

can be rewritten as

@(variable) first_expression_in_variable - second_expression_in_variable
