Step-by-step explanation:
∫(cos(1/x)/x² dx

Step-by-step explanation:
To get the inverse, swap the x- and y-variables, then solve for y. We should have the equation: 
Solving for y:
because
or 
So on interchanging the variable, we get the equation:
Answer:
5a
Step-by-step explanation:
Just use the reflexive property / reflexive angles, 5a = x and 4a equals the remaining side.
We are looking for the calories per minute....calories/minute.....
(4 1/2) / (2/3) =
(9/2) / (2/3) =
9/2 * 3/2 =
27/4 =
6 3/4 (or 6.75) calories per minute <==
