Answer:

No, and solutions is is not valid.

Step-by-step explanation:

Solving y'(x)= y(x)a|x| by parts yields y(x)= $e^{\frac{a}{2}x^{2} }$ is the solutions, for y(0)=0 (initial value), it yields $e^{0}=0$ which is not valid. Note a is assumed to be constant.

Please help me with number 2. I already have number 4. And leave a description on how to do it! Thank you!

Since your probably solving for W, isolate W by adding the -3n to both sides and get W=5n now use a calculator and multiply 5 and Pi. To Get 15.7.

I used N for pi since I don’t have that symbol

You need to specify what needs to be solved so I just assumed W

If sin(x) = squareroot 2 over 2 what is cos(x) and tan(x)

Bumek [7]

Answer:

cos(x) = square root 2 over 2; tan(x) = 1

Step-by-step explanation:

$\frac{\sqrt{2} }{2}$

was, before it was rationalized,

$\frac{1}{\sqrt{2} }$

Therefore,

$sin(x)=\frac{1}{\sqrt{2} }$

The side opposite the reference angle measures 1, the hypotenuse measures square root 2. That makes the reference angle a 45 degree angle. From there we can determine that the side adjacent to the reference angle also has a measure of 1. Therefore,

$cos(x)=\frac{1}{\sqrt{2} }=\frac{\sqrt{2} }{2}$ and

since tangent is side opposite (1) over side adjacent (1),

tan(x) = 1
