Write the sum without sigma notation. Then evaluate. 3 2 (-1)*+ sin k K = 1 Write the sum without sigma notation. (- 1) + sin + + (-1)'sin = +(-1)3+ sin (Do not simplify. Do not evaluate.) Evaluate the sum. 3 2 (1)*+ 1 sin - = K k =1 (Simplify your answer. Type an exact answer, using radicals as needed.)
