(1-1/2)+(1/2-1/3)+(1/3-1/4)+···+（1/2009-1/2010
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.

花卷怎么卷好看简单
要卷好看简单的花卷，可以按照以下步骤进行： 1. 准备工作：洗净头发，吹干至半干状态，以便能够更好地定型和卷发。 2. 分区：将头发分成几个区域，比如上下左右四个区域，使用夹子将其他区域的头发固定住，只取一部分头发来卷发。 3. 加热工具：使用电卷棒或卷发器等加热工具，根据个人喜好选择大小适宜的卷发棒。温度一般控制在180℃-200℃之间。 4. 卷发手法：从发尾开始，将一小束头发固定在卷发棒上，然后逆时针或顺时针转动卷发棒，将头发卷起。注意不要卷到发根部分，以免卷发过于蓬松。 5. 保持时间：将头发挂在卷发棒上约10-15秒钟，然后轻轻松开卷发棒。 6. 定型喷雾：在所有头发卷完之后，可以使用定型喷雾或发胶来固定卷发，增加卷发的持久性。 7. 整理发型：用手指轻轻整理卷发，使卷发看起来更加自然蓬松。 温馨提示：卷发过程中要注意防烫，避免将手或脸部皮肤接触到加热工具。在使用加热工具后，要等待其冷却后再整理头发，避免烫伤。平时也要注意保护发质，使用滋养发膜或保湿喷雾等护理产品，避免干燥和损伤。
