$\rule{100mm}{0.1mm}$

$\cot^2(2x)+\cos^2(2x)+\sin^2(2x)=\csc^2(2x)$

$\dfrac{\cos^2(2x)}{\sin^2(2x)} +[(\cos^2(2x)+\sin^2(2x)]=\csc^2(2x)$

$\dfrac{\cos^2(2x)}{\sin^2(2x)} +1=\csc^2(2x)$

$\dfrac{\cos^2(2x)+\sin^2(2x)}{\sin^2(2x)}=\csc^2(2x)$

$\dfrac{1}{sin^2(2x)} =\csc^2(2x)$

$\boxed{\csc^2(2x)=\csc^2(2x)}$ ✔

Mathematics

Algebra helps in the representation of problems or situations as mathematical expressions. It involves variables like x, y, z, and mathematical operations like addition, subtraction, multiplication, and division to form a meaningful mathematical expression. ... One simple example of an expression in algebra is 2x + 4 = 8.
