According to trigonometry,sine function is an odd function having periods of 2pi.

And it is a wavy function.

sine function is defined as the ratio between the side in front of the given angle and the hypotenuse

Answer:

Step-by-step explanation:

In trigonometry it expresses the ratio of the opposite side / the hypotenuse of the angle you are given.

For example if you want the sin of 38 degrees, you would put sin(38) =

and the answer would come out as 0.616 roughly. That would mean that if one of the acute angles in a right triangle was 38 degrees and the oppose side length was divided by the hypotenuse, the ratio would be 0.616 approximately.

No matter how big the triangle was to start with, as long as there was a right angle in it and one of the other angles was 38 degrees, then the ratio would be 0.616 between the opposite side and the hypotenuse.

In the diagram below the ratio of BC / AC is the Sin(A). If it is 38 degrees then Sin(A) = BC / AC = 0.616 not matter how big the triangle is.

Solve the differential equation. y' + 5xey = 0.

Gwar [14]

Answer:

The solution is $y = - ln(\frac{5}{2}x^{2} + C)$

Step-by-step explanation:

To solve the differential equation, we will find $y$

From the given equation, y' + 5xey = 0.

That is, $y' + 5xe^{y} = 0$

This can be written as

$\frac{dy}{dx} + 5xe^{y} = 0$

Then,

$\frac{dy}{dx} = - 5xe^{y}$

$\frac{dy}{e^{y}} = - 5x dx$

Then, we integrate both sides

$\int {\frac{dy}{e^{y}}} =\int {- 5x dx}$

$\int {e^{-y}dy }} =\int {- 5x dx}$

Then,

$-e^{-y} = -\frac{5}{2}x^{2} + C$

$e^{-y} = \frac{5}{2}x^{2} + C$

Then,

$ln(e^{-y}) = ln(\frac{5}{2}x^{2} + C)$

Then,

$-y = ln(\frac{5}{2}x^{2} + C)$

Hence,

$y = - ln(\frac{5}{2}x^{2} + C)$

Whenever you have a limit and the answer to that limit is one of the indeterminant form, you can use the L'Hopital's Rule to solve for the limit.

<u>Indeterminant forms:</u>

$\frac{0}{0} , \frac{\infty}{\infty}, 0\cdot \infty, \infty - \infty, 0^{0}, \infty^{0}, 1^{\infty}$

<u>L'Hopitals Rule:</u>

L'Hopitals rule is just taking the derivative of the numerator, and the derivative of the denominator separately.

After doing the L'Hopital's rule, take the limit again. If the result is an actual number then you got your answer.

If the result is another indeterminant form then use L'Hopitals rule again and check the limit again after that. Repeat the process until you get your answer.
