Cot? 2x + cos2x + sin’ 2x = csc? 2x<br> Need help with 40

kkurt [141]

Answer:

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

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

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

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

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

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

$\boxed{\csc^2(2x)=\csc^2(2x)}$ ✔

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