Is the cotan(theta) function the same as tan^-1(theta)?

    \[\cot \theta = \frac{ 1 }{ \tan \theta }\]

    So that's a yes? If I'm entering it into my calculator (there is no cot function), I enter\[\cot(\theta) = \tan^{-1}(\theta)\]

    you can't write it as \[\tan ^{-1} \theta \]

    Isn't that the same thing...? Doesn't: \[\frac{ 1 }{ \tan(\theta) } = \tan ^{-1}(\theta)\]

    nope. to find cot(theta), do this: 1/(tan(theta))

    when we take tan function from one side of equality to other then we write tan^-1

    So you use tan^-1 in something like... To solve for x if tan(x)=a, then x=tan^-1(a)

    Can you say\[\csc ^{4}(\theta) = \frac{ 1 }{ \sin ^{4}(\theta) }\]

    yep. in calculator, that would be: 1/(sin(theta))^4

    -1 is a special case in trigonometric functions.. -1 corresponds to inverse function.. thus for 1/sin, we use cosec and likewise..
