(1 point) In this problem, please evaluate the trig functions without a calculator and do not use a decimal point in your answer. An equation of the tangent line to the curve y - sin(x) at x - 77/6 is y = (x - 77/ 6) . An equation of the tangent line to the curve y - cos(a) at ac - 7/2 is y = -+ (3 - 7 / 2)
