The value of \( \sec^2(\tan^{-1} 3) + \csc^2(\cot^{-1} 2) \) is equal to:
The value of \( \sec^2(\tan^{-1} 3) + \csc^2(\cot^{-1} 2) \) is equal to:
Show Hint
Don't bother converting the inverse tan into a secant using triangles unless you have to. Using the $1+\tan^2$ identity is almost always faster.
