Answer:

The derivative is \frac{\cos x - \sin x-1}{e^x}

Step-by-step explanation:

(\frac{\sin x+1}{e^x}+2)'=\frac{e^x\cos x-e^x(\sin x +1)}{e^{2x}}=\frac{\cos x - \sin x-1}{e^x}

To do this problem, we have to divide fractions. If you don't know what dividing fraction is I'mgoign to tell you how to do it

<u>How to divide fractions</u>

To Divide fractions, you have to pick the one that is going to be divided and the one that's going to be divided by. Like the dividend and the divisor. Let's say we have 1/2 divided by 1/2.

One important rule in dividing fractions is always flipping the second fraction. If we have 1/2 as the second fraction, we flip it to 2/1 or 2. This action is called the reciprocal.

Once we changed the second fraction to a reciprocal, we multiply the fractions like 1/2 times 2/1 and then we get the answer, 2/2 which equal to one.

If you want, do some practice problems before we do this problem so you can get comfortable with it

1) 2/3 divided by 6/5

2) 4/5 divided by 1/2

3)5/6 divided by 7/8

Now let's get to this problem.

<u>Solving this question</u>

<u />

The first step in solving this question is finding what we need divided by and what we are using to divide by.

What we are dividing is the 5

We can set the equation up like 5/6 divided by 5/1 we have to flip the second fraction: 5/1. We get 1/5. Now let's multiply

5/6*1/5=1/6

So, the answer is 1/6 pounds

I hope this helped

Sin x =<br>cos x =<br>tan x =​
madreJ [45]

Answer:

Step-by-step explanation:

Use SOH CAH TOA to recall how the trig functions fit on a triangle

SOH: Sin(Ф)= Opp / Hyp

CAH: Cos(Ф)= Adj / Hyp

TOA: Tan(Ф) = Opp / Adj

so Sin(x) = d/f

Cos(x) = e/f

Tan(x) = d/e

got it? :)
