We seek to prove the identity: sin2( −x) −cos2( −x) sin( −x) −cos( − x) ≡ cosx − sinx. Consider the LHS: LH S = sin2( −x) −cos2( − x) sin( −x) −cos( − x) Using the fact that sine is and function and cosine is an even function we have: sin( − x) = − sin(x) and cos( − x) = cos(x) Then: LH S = sin2(x ... WebIn mathematics, an "identity" is an equation which is always true. These can be "trivially" true, like " x = x " or usefully true, such as the Pythagorean Theorem's " a2 + b2 = c2 " for right triangles.
