WebForm 4 & 5 Unit 10 Lesson 5: Calculating angles / Finding Unknown Angles Form 4 & 5 Unit 10 Lesson 6: Which ratio to usage (sine, cosine and tangent altogether) Form 4 & 5 Unit 10 Teaching 7: Sine, Cost real Tangent by whatsoever angle (acute, obtuse and reflex) WebThe sum formula works whether both angles are the same or different: sin (A + B) or sin (A + A). However, sin (A + A) is really sin 2A. So, sin 2A is sin A cos A + cos A sin A. They are both the same product, in opposite order, so this statement can be simplified to sin 2A = 2 sin A cos A. Similarly, cos 2A = cos A cos A - sin A sin A,
