Jul 23, 2018 ... The value of Sin A + Cos A actually depends on the variable 'a' so we can not actually prodict out the exact answer to this question. Apr 5, 2018 ... The distance between the points ( cosA, sinA ) and ( -sinA, cosA ) is · Expert-Verified Answer · √2 is The distance between the points ( cosA, ... Given sinA = cosA We know that sin 45 = cos45 = 1/ root2 Hence, A = 45 degrees Therefore, 2tan 2 A + sin 2 A - 1 = 2tan 2 45 o + sin 2 45 How can you prove that (cos^2 A-sin^2 B) / (sinA cosA+sinB cosB) =cot(A+B)? The RHS should be cot(A+B). Definition of Sec and Tan = 1/Cos2A - Sin2A/Cos2A Combining Fractions = (1 - Sin2A) / (Cos2A) Apply Double Angle Formula = (1 - 2SinACosA Dec 17, 2020 ... Calculation: (sinA + cosA)/(sinA – cosA) = 5/4 ⇒ 4(sin A + cos A) = 5(sin A – cos A) ⇒ 4sinA + 4cosA = 5sinA – 5cosA ⇒
