Answer:
The value of Cos(01) is 0.866 or √3/2
Step-by-step explanation:
In this question, we are asked to calculate the value of cos (01) given the value of sin(01)
Now, given the value of sin (01), we can calculate the value of cos (01).
To get the value of 01, we simply find the value of the arc sin 01
Mathematically since sin (01) = 1/2
(01) = arc sin (1/2)
(01) = 30 degrees
Now since 01 = 30 degrees
cos 01 = Cos (30) = 0.8666 or simply √3/2
For this case we have that the expression in its exact form is the same, that is:
If it is expressed in decimal form we have:
If we want equivalent expressions, we must first mention the following property of powers and roots:
Then, we can rewrite the expression as:
Answer:
