Suppose that the voltage vector of the heart vt changes from one beat to the next according to the equation vt + 1 = 1 0 0 −1 vt. If the voltage vector during the current heartbeat is 0.9 −0.4 , what was the voltage vector in the previous heartbeat?

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.
