​

i think its help..............

Step-by-step explanation:

we would like to integrate the following integration

in order to do so rewrite

we can also rewrite cos²(x) by using trigonometric indentity

to apply u-substitution we'll choose

thus substitute:

apply substraction integration and:

use constant integration rule:

use exponent integration rule:

back-substitute:

finally we of course have to add constant of integration:

if you are looking for the unit rate then the answer would be 9 because unit rate is distance divided by time.
