Help with one integral problem?

Illusion [34]

Answer: $2\sqrt{1+tant}+C$

Step-by-step explanation:

To integrate means to find the antiderivative of the function. For this problem, we can use u-substitution.

$\int\limits {\frac{dt}{cos^2t\sqrt{1+tant} } } \$

Let's first use our identities to rewrite the function. Since $\frac{1}{cosx} =secx$ , we can use this identity.

$\int\limits {\frac{sec^2t}{\sqrt{1+tant} } } \,$

$u=\sqrt{1+tant}$

$du=\frac{sec^2t}{2\sqrt{1+tant} } dt$

Now that we have u and du, we can plug them back in.

$\int\limits {2} \, du$

$\int\limits{2} \, du=2u$

Since we know u, we can plug that in.

$2\sqrt{1+tant}$

This may seem like the correct answer, but we forgot to add the constant.

$2\sqrt{1+tant}+C$

each can of paint will cover 450 tiles. Augustin is painting 300 tiles in his bathroom, 675 in his kitchen, and 100 in his hallw

nydimaria [60]

Well, first you must find the total amount of tiles that Augustin needs to paint.
So, 300 from the bathroom
675 from the kitchen
+ 100 from the hallway
--------------------
All together, 300+675+100=1075.
Because each can covers 450 tiles, and you are trying to find how many cans you Augustin needs, you woud divide 1075 by 450.
1075/450 is 2.38888888 is not a full number, and you can not have part of a can. You also would not round downward, because then you wouldn't paint all the tiles. Therefore, you would round upward to 3.
Augustin will need 3 cans of paint.
