Answer:
Windmill
Explanation:
The Windmill is a technological structure that was created to function using the power or speed of the wind.
The speed generated by the wind was used by the windmill for various purposes.
Those purposes includes:
a. Generation of electric power also known as electricity.
b. Pumping of water.
c. Milling of grains.
d. Generation of other sources of energy
A wind mill is made of fan or blade like structures that are called VANES. This vanes utilises the speed of the wind which cause them to rotate continuously at a very high speed and allows them to generate the energy required to mill grains, pump water or generate electricity.
Answer:
sec(4x) + C
Explanation:
original problem: ∫sec(4x)tan(x)dx
use integration by substitution (u-sub) by setting u = 4x
if u = 4x, then du/dx = 4 and du = 4dx (dx = du/4)
after substitution the integral is ∫sec(u)tan(u)(du/4)
move the 1/4 out of the integral by using the integral Constant rule to form 1/4∫sec(u)tan(u)du
the anti-derivative of sec(u)tan(u) is sec(u), memorize your trigonometric derivatives!!!!
after integration, we get sec(u)/4 + C , now plug u back into the equation
sec(4x) + C is the general solution
15:35
divide both sides by 5 if you need it in simplest form
