Question

simplificar cotx cscx secx (1-cos^2x)

Answer 1

Recordemos las identidades que usaremos:

• ctgx = cosx / sen x
• cscx = 1 / senx
• secx = 1 / cosx
• sen²x = 1 - cos²x

Procedimiento:
${\cot x.\csc x. \sec x.(1-\cos x)}\\\\{ \frac{\cos x}{\sin x}. \frac{1}{\sin x}. \frac{1}{\cos x}.\frac{\sin ^2x}{1}\ \ \ \ \ simplificando:}\\\\{\boxed{1}}$


Salu2.!! :)
