2018年2月14日 · (i) cos 50° sin 40° + sin 50° cos 40° To find: (i) The solution of the given expression. Solution: We know that . cos x° = sin (90°-x°) So, cos 50° = sin (90°-50°) = sin 40° Thus, cos 50° sin 40° = sin 40° sin 40° = sin² 40 ° Again, sin x° = cos (90°-x°) So, sin 50° = cos (90°-50°) = cos 40° Thus,
