1 / | | sin(2*x) | 4*cos(2*x)*5 dx | / 0
Integral((4*cos(2*x))*5^sin(2*x), (x, 0, 1))
There are multiple ways to do this integral.
Let .
Then let and substitute :
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 an exponential function is itself divided by the natural logarithm of the base.
Now substitute back in:
So, the result is:
Now substitute back in:
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 an exponential function is itself divided by the natural logarithm of the base.
So, the result is:
Now substitute back in:
Add the constant of integration:
The answer is:
/ | sin(2*x) | sin(2*x) 2*5 | 4*cos(2*x)*5 dx = C + ----------- | log(5) /
