Haya la integral de xarcsenx/((1-x^2)^1/2). Utiliza la sustitución de t= arcsenx
ikadub [295]

Answer:

<em>Explicación más abajo</em>

Step-by-step explanation:

Integración Indefinida

La integral

I=\int \dfrac{x .arcsen\left(x\right)}{\sqrt{1-x^2}}

Se resuelve con el cambio de variables:

t=arcsen(x)

Una vez hechos los cambios, la integral se resuelve en función de t:

I=sen(t)-t.cos(t)+C

Hay que devolver los cambios para mostrarla en función de x.

El cambio de variables también se puede escribir:

x=sen(t)

Recordando que

cos(t)=\sqrt{1-sen^2(t)}

Entonces:

cos(t)=\sqrt{1-x^2}

Devolviendo los cambios:

I=sen(t)-t.cos(t)+C=x-arcsen(x)\sqrt{1-x^2}+C

Es la respuesta correcta

If sinθ&lt;0 and cosθ&gt;0, then the terminal point determined by θ is in:
alukav5142 [94]

Answer:

D.) Quadrant 4

Step-by-step explanation:

Sin theta < 0 tells us the angle is in quadrant 3 or 4

The y component is negative

Cos theta >0 tells us the angle is in quadrant 1 or 4

The x component is positive

Therefore theta must be in quadrant 4

JJ decided to leave a tip that is 15% of the original price for his meal. How much should he leave as tip for the $5.50 cheesebu
Nitella [24]

If JJ decided to leave a tip that is 15% of the original price for his meal, he should leave $1.2 as tip for the $5.50 cheeseburger and $2.50 milkshake.

<h3>How to calculate discount?</h3>

According to this question, JJ bought a $5.50 cheeseburger and a $2.50 milkshake.

This means that in total, JJ purchased $5.50 + $2.50 = $8 worth of meal.

If he decided to leave a tip that is 15% of the original price of his meal, hence,

15/100 × $8 = $1.2

Therefore, if JJ decided to leave a tip that is 15% of the original price for his meal, he should leave $1.2 as tip for the $5.50 cheeseburger and $2.50 milkshake.

(a) if g(x) = x2 − 3x + 3, find g'(a) and use it to find equations of the tangent lines to the curve y = x2 − 3x + 3 at the poin
iVinArrow [24]
Using the power rule, g'(a) = 2x-3.

At x = 0, g'(0)=-3. Therefore, the slope of the tangent line is -3. In point-slope form, the equation of the line tangent to the curve at (0,3) is y-3=-3(x-0). 

At x = 2, g'(2)=1. Therefore, the slope of the tangent line is 1. In point-slope form, the equation of the line tangent to the curve at (2,1) is y-1=1(x-2).
