To find the sum of the given series, we need to add all the terms together. (1 - 1/2) + (1/2 - 1/3) + (1/3 - 1/4) + ... + (1/2009 - 1/2010) We can simplify each term by finding the common denominator. 1 - 1/2 = 2/2 - 1/2 = 1/2 1/2 - 1/3 = 3/6 - 2/6 = 1/6 1/3 - 1/4 = 4/12 - 3/12 = 1/12 We can observe that each term follows this pattern - the denominator of the second fraction becomes the denominator of the first fraction in the next term. So, the series can be written as: 1/2 + 1/6 + 1/12 + ... + 1/2009 To find the sum of this series, we need to find the common denominator of all the fractions. The common denominator of 2, 6, 12, ..., 2009 will be the least common multiple (LCM) of these numbers. Calculating the LCM of these numbers is a bit lengthy. Instead, we can find the LCM of 2, 3, 4, ..., 2010, and then divide by the LCM of 2, 3, 4, ..., 2009. LCM(2, 3, 4, ..., 2010) / LCM(2, 3, 4, ..., 2009) = 2010 / 2 = 1005 So, the common denominator is 1005. To add the fractions, we need to express them with the common denominator: 1/2 = (1/2) * (1005/1005) = 1005/2010 1/6 = (1/6) * (1005/1005) = 167.5/2010 1/12 = (1/12) * (1005/1005) = 83.75/2010 Now we can add: 1005/2010 + 167.5/2010 + 83.75/2010 + ... + 1/2009 We can observe that the denominators of the fractions form an arithmetic sequence, and the numerators follow the same pattern. Using the formula for the sum of an arithmetic sequence: Sum = (first term + last term) * number of terms / 2 In this case, the first term is 1005/2010, the last term is 1/2009, and the number of terms is 2010. Sum = (1005/2010 + 1/2009) * 2010/2 Sum = (1005/2010 + 1/2009) * 1005 Sum = (1005 * 2009 + 1 * 2010) / 2 Sum = (2019955 + 2010) / 2 Sum = 2021965 / 2 Sum = 1010982.5 Therefore, the sum of the given series is 1010982.5.

我家宝宝,昨天早上起来全身和脸上都有红色小点,请教下怎么办

我不是医生,但是这种情况可能是由多种原因引起的,例如过敏、荨麻疹、病毒感染等。以下是一些建议: 1.观察症状:注意观察宝宝是否有其他不适症状,如发热、喉咙痛、呼吸困难等。如果有明显不适或症状加重,请及时就医。 2.排除过敏源:如果你怀疑宝宝可能对某种食物、药物、洗涤剂或者宠物毛发等过敏,尽量避免接触这些物质,并观察症状是否改善。 3.保持皮肤清洁:轻柔地清洁宝宝的皮肤,可以用温水洗澡,避免使用刺激性的肥皂或洗涤剂。同时,尽量保持宝宝的皮肤干燥。 4.避免搔抓:如果宝宝感到瘙痒,尽量避免搔抓,可以给宝宝剪短指甲,或者穿长袖衣物遮盖小手。 5.保持室内清洁:保持室内空气清新,注意清洁宝宝周围的环境,尽量避免尘螨、宠物毛发等过敏源。 最重要的是,请及时咨询医生,并根据医生的建议进行治疗。只有医生才能给出正确的诊断和治疗方案。

蜡笔小新:房子被小新炸了!小新家的房贷都还没还完哦

在动画片《蜡笔小新》中,小新经常闹出一些令人啼笑皆非的事件。虽然故事中经常出现小新捣蛋导致房子遭到破坏,但我们不能将其同现实中的贷款问题混为一谈。小新家是否还有房贷还未还完,在剧情中并没有明确提及。 然而,在现实生活中,贷款是一种常见的购房方式。人们可以通过向银行或其他金融机构贷款来购买房屋,并按约定的时间和利率逐步还清借款。如果未能按时偿还贷款,可能会导致逾期费用或其他负面后果。 因此,贷款和房贷是一个需要严肃对待的话题。对于真实的贷款情况,我们应该妥善规划自己的财务情况,确保及时偿还贷款并遵守合同规定。
