2 key presses are needed
38%3= 1.14
1.14-sin (3)=1 since sin (3)=0.14

37 - (3*3*3) = 10 - (3*3) = 1

it is wrong because you reduced 37 to 1 but question is to reduce 38 to 1

Starting with any number at all, I can always reduce it to 4 by applying a consistent rule. 4 is the magic number.
Example: 100. 100 is 10, 10 is 3, 3 is 5, 5 is 4, and 4 is the magic number.
Another Example: 52. 52 is 8, 8 is 5, 5 is 4, 4 is the magic number.
Find out what is the rule?
