Find intergral (e^xcos(3x)dx

ArbitrLikvidat [17]

Answer:

Hello,

Step-by-step explanation:

Here is an other method than classical:

$I=\int {e^x*cos(3x)} \, dx =e^x*(k_1/cos(3x)+k_2*sin(3x) )\\\\Let's\ derivate:\\\\e^xcos(3x)=e^x(k1*cos(3x)+k_2*sin(3x))+e^x*(k_1*(-sin(3x))*3+k_2*cos(3x)*3)\\\\By\ identification:\\\\\left\{\begin{array}{ccc}k_1+3k_2&=&1\\-3k_1+k2&=&0\\\end{array}\right.\\\\\\\left\{\begin{array}{ccc}k_1&=&\dfrac{1}{10}\\k2&=&\dfrac{3}{10}\\\end{array}\right.\\\\\\\boxed{I=e^x(\dfrac{1}{10}*cos(3x)+\dfrac{3}{10}*sin(3x))}\\$

What is the measure of x

Dafna1 [17]

Answer:

58 degrees

Step-by-step explanation:

XYZ is 90 degrees. XYO is 32 degrees. Angle x takes up the space leftover in the right angle, so simply subtract 32 from 90.

90-32= 58

Hope this help! (if it does pls consider giving me brainliest)

Find the area of the circle with the given radius or diameter. Use = 3.14.

masya89 [10]

Radius [ r ] = 6 units

Area of a circle = $\pi r^{2}$ = $3.14 * 6 * 6 = 3.14 * 36 = 113.04$ sq. units.

Hence, the answer is B.

Use the pi key on a scientific or graphing calculator to compute the percent of error of the approximation of pi, 3.14, to the v

Kitty [74]

Percent error is calculated as $\frac{approximation-theoretical}{theoretical}*100$ .
The approximation in this case is 3.14, and the theoretical or actual value is pi.

Using the formula, the percent error will be:
$\frac{3.14- \pi }{ \pi }*100$ = -0.0507%
