Verify the identity. tan2(u) sin(u) = tan(u) sin(u) - sin2(u) tan(u) - sin(u) = = ====== sin2(u) cos(u) cos(u) = sin(u)-( sin2(u). cos(u) cos(u)
Verify the identity. tan2(u) sin(u) = tan(u) sin(u) - sin2(u) tan(u) - sin(u) = = ====== sin2(u) cos(u) cos(u) = sin(u)-( sin2(u). cos(u) cos(u) (1 )(1 - cos(u)) cos(u) tan(u) sin(u)
