示例：反三角函数
使用反三角函数获得各个三角函数的值 (单位为弧度)。
1.
以符号形式计算函数
sin
和
cos
。
<region id="ID0EVPPEB" actualWidth="86.646666666666675" actualHeight="51.158666666666669" top="38.400000000000006" left="19.200000000000003" xmlns="http://schemas.mathsoft.com/worksheet50"> <math resultRef="30"> <symEval xmlns="http://schemas.mathsoft.com/math50"> <apply> <id labels="FUNCTION" label-is-contextual="true" xml:space="preserve">sin</id> <apply> <div /> <id labels="CONSTANT" label-is-contextual="true" xml:space="preserve">π</id> <real>2</real> </apply> </apply> <command> <placeholder /> </command> <symResult> <real>1</real> </symResult> </symEval> <resultFormat> <matrix size="12,12" offset="0,0" show-indices="false" expand-nested-arrays="false" /> </resultFormat> </math> </region>
<region id="ID0EDQPEB" actualWidth="88.920000000000016" actualHeight="51.158666666666669" top="38.400000000000006" left="172.8" xmlns="http://schemas.mathsoft.com/worksheet50"> <math resultRef="31"> <symEval xmlns="http://schemas.mathsoft.com/math50"> <apply> <id labels="FUNCTION" label-is-contextual="true" xml:space="preserve">cos</id> <apply> <div /> <id labels="CONSTANT" label-is-contextual="true" xml:space="preserve">π</id> <real>2</real> </apply> </apply> <command> <placeholder /> </command> <symResult> <real>0</real> </symResult> </symEval> <resultFormat> <matrix size="12,12" offset="0,0" show-indices="false" expand-nested-arrays="false" /> </resultFormat> </math> </region>
2.
使用返回值，以符号形式计算函数
acos
和
asin
。
<region id="ID0ERSPEB" actualWidth="94.640000000000015" actualHeight="51.158666666666669" top="96.000000000000014" left="19.200000000000003" xmlns="http://schemas.mathsoft.com/worksheet50"> <math resultRef="32"> <symEval xmlns="http://schemas.mathsoft.com/math50"> <apply> <id labels="FUNCTION" label-is-contextual="true" xml:space="preserve">asin</id> <real>1</real> </apply> <command> <placeholder /> </command> <symResult> <apply> <div /> <id labels="CONSTANT" xml:space="preserve">π</id> <real>2</real> </apply> </symResult> </symEval> <resultFormat> <matrix size="12,12" offset="0,0" show-indices="false" expand-nested-arrays="false" /> </resultFormat> </math> </region>
<region id="ID0E6SPEB" actualWidth="96.913333333333355" actualHeight="51.158666666666669" top="96.000000000000014" left="172.8" xmlns="http://schemas.mathsoft.com/worksheet50"> <math resultRef="33"> <symEval xmlns="http://schemas.mathsoft.com/math50"> <apply> <id labels="FUNCTION" label-is-contextual="true" xml:space="preserve">acos</id> <real>0</real> </apply> <command> <placeholder /> </command> <symResult> <apply> <div /> <id labels="CONSTANT" xml:space="preserve">π</id> <real>2</real> </apply> </symResult> </symEval> <resultFormat> <matrix size="12,12" offset="0,0" show-indices="false" expand-nested-arrays="false" /> </resultFormat> </math> </region>
返回值单位为弧度。
3.
数值形式计算相同的函数。
<region id="ID0ETUPEB" actualWidth="118.22" actualHeight="25.6" top="153.60000000000002" left="19.200000000000003" xmlns="http://schemas.mathsoft.com/worksheet50"> <math resultRef="34"> <eval xmlns="http://schemas.mathsoft.com/math50"> <apply> <id labels="FUNCTION" label-is-contextual="true" xml:space="preserve">asin</id> <real>1</real> </apply> <unitOverride> <placeholder /> </unitOverride> </eval> <resultFormat> <matrix size="12,12" offset="0,0" show-indices="false" expand-nested-arrays="false" /> </resultFormat> </math> </region>
<region id="ID0EBVPEB" actualWidth="120.49333333333334" actualHeight="25.6" top="153.60000000000002" left="172.8" xmlns="http://schemas.mathsoft.com/worksheet50"> <math resultRef="35"> <eval xmlns="http://schemas.mathsoft.com/math50"> <apply> <id labels="FUNCTION" label-is-contextual="true" xml:space="preserve">acos</id> <real>0</real> </apply> <unitOverride> <placeholder /> </unitOverride> </eval> <resultFormat> <matrix size="12,12" offset="0,0" show-indices="false" expand-nested-arrays="false" /> </resultFormat> </math> </region>
4.
使用不同值，重复函数
cot
、
acot
、
sec
、
asec
、
csc
和
acsc
之间的这种比较。
