Integral(x^7*cos(y), (x, 0, x - 4*cos(y)))
The integral of a constant times a function is the constant times the integral of the function:
The integral of is when :
So, the result is:
Add the constant of integration:
The answer is:
/ | 8 | 7 x *cos(y) | x *cos(y) dx = C + --------- | 8 /

(x - 4*cos(y)) *cos(y)
----------------------
8
=
8
(x - 4*cos(y)) *cos(y)
----------------------
8
(x - 4*cos(y))^8*cos(y)/8
