\bf \cfrac{cot(A)}{tan(A)}\implies \cfrac{~~(1)/(tan(A))~~}{tan(A)}\implies \cfrac{~~(1)/(tan(A))~~}{(tan(A))/(1)}\implies \cfrac{1}{tan(A)}\cdot \cfrac{1}{tan(A)} \\\\\\ \cfrac{1}{[tan(A)]^2}\implies \cfrac{1}{tan^2(A)}\implies \cfrac{1^2}{tan^2(A)}\implies \left( \cfrac{1}{tan(A)} \right)^2\implies cot^2(A)
