First integral:
Use the rational exponent to represent roots. You have
And from here you can use the rule
to derive
Second integral:
Simply split the fraction:
So, the integral of the sum becomes the sum of three immediate integrals:
So, the answer is the sum of the three pieces:
Third integral:
Again, you can split the integral of the sum in the sum of the integrals. The antiderivative of the cosine is the sine, because . So, you have
Answer:
the answer is 4
