Cos pie by 3
WebJan 2, 2024 · The cosine difference identity is found by simplifying Equation (2) by first squaring both sides: (cos(A − B) − 1)2 + (sin(A − B) − 0)2 = (cos(A) − cos(B))2 + (sin(A) − sin(B))2 Then we expand both sides [cos2(A − B) − 2cos(A − B) + 1] + sin2(A − B) = [cos2(A) − 2cos(A)cos(B) + cos2(B)] + [sin2(A) − 2sin(A)sin(B) + sin2(B)]
