To evaluate ∫ 3x2 cos (2x3 - 4) dx, it is necessary to let A. u = 2x3 -4 B. u = 3x2 C. u = 6x. D. u = 6x2
vodomira [7]
When integrating, u-substitution is used to make things easier to work out. In u-substitution, the "u" is generally determined if its derivative is in the expression. That way when integrating with respect to "u", you can just replace the derivative of the u with "du" and easily integrate. 

For this question, it would be easiest to let:
u=2x^3

Let's take the derivative of u and see if we can work something out:
du = 6x^2

We have an x² in the integral expression, and therefore, it's valid for us to let u = 2x³. Thus, your answer is A.

If f(x)=3x^2 +1 and g(x)=1-x, what is the value of (f-g)(2)
liraira [26]

(f-g)(x)=3x^2+1-(1-x)=3x^2+1-1+x=3x^2+x\\\\ (f-g)(2)=3\cdot2^2+2=14

I don't understand how to do things like 5 divided by 1/3.​
podryga [215]

No worries

First write 5 as 5/1.

Then, our division becomes:

5/1 ÷ 1/3

Then we just need to turn on second number upside down and multiply.

5/1 × 3/1

= 15/1

=> 15
