Sejam u = (2, −7), v = (1, 6) e w = (√ 3, −π) vetores do plano. Calcule os seguintes vetores: a) u + 2v b) u + v − w c) 3u − 1 πw d) 2u − 3v + (0, ...

a) u + 2v = (2, -7) + 2(1, 6) = (2, -7) + (2, 12) = (4, 5) b) u + v - w = (2, -7) + (1, 6) - (√3, -π) = (2+1-√3, -7+6+π) = (0.268, -0.141) c) 3u - πw = 3(2, -7) - π(√3, -π) = (6, -21) - (√3π, -π²) = (6-√3π, -21+π²) d) 2u - 3v + (0, 3) = 2(2, -7) - 3(1, 6) + (0, 3) = (4, -14) - (3, 18) + (0, 3) = (1, -29)
