Question

Write the given expression as the cosine of an angle. ​

Quizplus · Accepted Answer

The expression is in the format of a hexadecimal number. We need to convert it to decimal and divide by 2^32, which gives us approximately 0.345. This is the cosine of an angle in radians, which can be found using a calculator or a reference sheet to be approximately 1.230 radians or 70.51 degrees. Therefore, the expression can be rewritten as cos(1.230). Choice B corresponds to this value.
