Prove that: (cosA - sinA + 1) / (cosA + sinA +1) = (1 - sinA) / cosA. Answer: For solving this questions we need to rationalize the denominator. 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. Sep 16, 2002 ... sina. sinA. = sinb. sinB. = sinc. sinC.

Calculation: (sinA + cosA)/(sinA – cosA) = 5/4 ⇒ 4(sin A + cos A) = 5(sin A – cos A) ⇒ 4sinA + 4cosA = 5sinA – 5cosA ⇒ Solve for a variable, factor, expand, evaluate fractions, linear equations, quadratic equations, inequalities, systems of equations, matrices.
