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

Writing down your grades after each test gives you an accurate and recent set of data to consistently look at and monitor. Whether you progress or degrees, you are still monitoring the data.
Answer: Electron
Explanation:
Two type of microscopes that are used to view cells are optical and the electron microscopes.
The optical microscope, is also called the light microscope, and it uses visible light and lenses to magnify small objects and make them bigger. It is used in viewing cells as they appear big.
Electron microscope gives a high resolution images of specimens. The electron microscope is used in medicine to investigate tissues, cells, etc.
Answer: B
Explanation: the bond that a mother and infant form is a bond that could and should last a life time. The bond is how the child knows who its mother is from birth verses everyone else around the child.
