2. **第二次循环**:`op1`被自增为`minus`(即1)。执行`case minus`分支,计算`x-y`(10-20=-10),输出-10。 3. **第三次循环**:`op1`继续自增为`times`(即2)。执行`case times`分支,计算`x*y`(10*20=200),输出200。循环结束后`op1`值变为3,不再满足条件`op1<=times`(即`op1<=2...
What is the value of x in the equation 3x minus 4y equals 65, when y equals 4? What equation is equal to 2 \cos 30^o \cos 10^o? Which value of x will satisfy the equation 0.4(5x - 1470) = x? a. 490, b. 2,130 or c. 1,470?
Answer to: Verify the identity. sin x plus or minus sin y / cos x + cos y = tan x plus or minus y / 2 By signing up, you'll get thousands of...
Hero’s argument is a little peculiar. We need to know that the example taken is general and not just an odd instance where half the area of the circle, taking the circumference as 3·diameter, equals (, withbequal to the diameter andhthe radius. In any case, one would quickly see t...
For example, element b: b/Z rounded equals the number of modules wide b is equal to. All eight elements in turn would be decoded by dividing each by Z. The total of all eight elements must equal 16 modules. The decoded sequence may then be converted to binary bits; still referring ...
