角度运算主要包括角度单位的换算,角度的和、差,角度的扩大与缩小等.下面我们说说各种运算的口诀与方法.一、度化为度、分、秒口诀:零点几度乘六十,整数部分记为分;不足一分继续乘,其积便是秒大小.例1计算:45.56°=____°____′____″.解:先把不足1°的0.56°化为分(乘60),得(0.56×60)′=33.6′,再把不足1′的0.6′化为秒(乘60),得(0.6×60)″=36″.因此,45.56°=45°33′36″.
Angle calculation includes the conversion of the angle unit, the angle and the difference, the angle of expansion and contraction, etc. Here we talk about a variety of computing formulas and methods. First, the degree of degree, minutes, seconds Formula: zero degrees multiplied by Sixty, the integer part of the points for the points; less than one point to continue to multiply, the product is the second size. Example 1 Calculation: 45.56 ° = ____ ° ____’____ “. Solution: first less than 1 ° of 0.56 ° into points Multiply 60 to obtain a value of (0.56 × 60) ’= 33.6’, and then subtract 0.6 ’from a value of 1’ to a value of 60 to obtain a value of (0.6 × 60) ”= 36.“ Therefore, 45.56 ° = 45 ° 33 ’36 ”.
