Split 7575 into two angles where the values of the six trigonometric functions are known.

cot(30+45)cot(30+45)

Apply the sum of angles identity.

cot(30)cot(45)−1cot(45)+cot(30)cot(30)cot(45)-1cot(45)+cot(30)

The exact value of cot(30)cot(30) is √33.

√3cot(45)−1cot(45)+cot(30)3cot(45)-1cot(45)+cot(30)

The exact value of cot(45)cot(45) is 11.

√3⋅1−1cot(45)+cot(30)3⋅1-1cot(45)+cot(30)

The exact value of cot(45)cot(45) is 11.

√3⋅1−11+cot(30)3⋅1-11+cot(30)

The exact value of cot(30)cot(30) is √33.

√3⋅1−11+√33⋅1-11+3

Simplify √3⋅1−11+√33⋅1-11+3.
