I'm new on matlab and I need to find the value that make the derivative of a function = 0 in order to find the maximum of my function(adsbygoogle = window.adsbygoogle || []).push({});

I started by defining the variable T

>> syms T

Then I but my function

>> f=((((cos(T))^2+(sin(T)*cos(T)))^2)+3*(((sin(T))^2+(sin(T)*cos(T)))^2))^(0.5)

Then I diffrentiate the function with respect to T

>> diff(f,T)

But know i want to find the value that make my function equal to zero but I cant figure it out espically that I'm new on matlab

If anybody can help me I'll be thankfull
