Integral(8^x - 5*sin(4*x) + 7, (x, 0, 1))
Integrate term-by-term:
The integral of an exponential function is itself divided by the natural logarithm of the base.
The integral of a constant times a function is the constant times the integral of the function:
The integral of a constant times a function is the constant times the integral of the function:
Let .
Then let and substitute :
The integral of a constant times a function is the constant times the integral of the function:
The integral of sine is negative cosine:
So, the result is:
Now substitute back in:
So, the result is:
So, the result is:
The integral of a constant is the constant times the variable of integration:
The result is:
Now simplify:
Add the constant of integration:
The answer is:
/ | x | / x \ 5*cos(4*x) 8 | \8 - 5*sin(4*x) + 7/ dx = C + 7*x + ---------- + ------ | 4 log(8) /
