Quickly learn how to prove the trigonometric identity sin(a+b) = sin(a)cos(b) + cos(a)sin(b)! This clear and simple explanation makes understanding algebra and trigonometry easy for everyone.
sin(a+b) = sin(a)cos(b) + cos(a)sin(b) Proof • sin(a+b) = sin(a)cos(b) + cos(a)sin(b) Proof
cos(a+b) = cos(a)cos(b) - sin(a)sin(b) Proof • cos(a+b) = cos(a)cos(b) - sin(a)sin(b) Proof
tan(a+b) = tan(a)+tan(b) / (1-tan(a)tan(b)) Proof • tan(a+b) = tan(a)+tan(b) / (1-tan(a)tan(b)...
sin(a-b) = sin(a)cos(b) - cos(a)sin(b) Proof • sin(a-b) = sin(a)cos(b) - cos(a)sin(b) Proof
cos(a-b) = cos(a)cos(b) + sin(a)sin(b) Proof • cos(a-b) = cos(a)cos(b) + sin(a)sin(b) Proof
tan(a-b) = tan(a)-tan(b) / (1+tan(a)tan(b)) Proof • tan(a-b) = tan(a)-tan(b) / (1+tan(a)tan(b)...
