cotg²x - cos²x
=1/(tan²(x))-cos²(x)
=cos²(x)/sin²(x)-cos²(x)
=(cos²(x)-cos²(x).sin²(x))/sin²(x)
=(cos²(x))(1-sin²(x))/sin²(x)
=(cos²(x)).(cos²(x))/sin²(x)
=cos²(x)/tan²(x)
=
cotg²x .cos²x

Bonsoir Simplifier les expressions suivantes : A = 1 + 2 cos a + cos 2a B = 1 + 2 sin a - cos 2a C = ( 1 - cos a + sin a ) / ( 1 + cos a + sin a ) Merci
