Hello,

I'm seeking advice on interpreting exponents in trigonometric expressions, specifically for [tex]cos(x+1)^2[/tex]. Should the exponent apply to the whole function as [tex](cos(x+1))^2[/tex], or only to the argument, implying [tex]cos((x+1)^2)[/tex]? This has become a point of confusion in a mathematical context, particularly with trigonometric functions. Any clarification or reference to standard mathematical conventions would be highly appreciated.

Thank you!
