The product rule?

d[fg(x)]/dx = df(x)/dx*g(x) + f(x)*dg(x)/dx or (fg)' = f'g + fg'


How do you simplify algebraic questions Example 8d-5 plus 7d-9d?

To simplify 8d -5 +7d -9d, combine the numbers with the ds and don't forget the -5. 8d + 7d - 9d = 6d Simplified, it is 6d - 5.


If y equals the integral from 5x on top to cosx on bottom of cos of u squared du what is y'?

y=S^5x _cos(x) cos(u²) du The derivative of a definite integral of a function f(x) is equal to the difference in the product of the function at each limit of integration times the limit of integration. y'=cos(u²)*du/dx from u=cos(x) to u=5x y'=-sin(x)*cos(cos(x)²)-5*cos(25x²) To understand why this works, consider the following where F(x) is the antiderivative of f(x) y=F(g(x))-F(h(x))=S f(x)dx from h(x) to g(x) If you take the derivative of this expression and apply the chain rule dy/dx = dF(g(x))/dx - dF(h(x))/dx = f(g(x))*dg/dx - f(h(x))*dh/dx


ALT?

DefinitionAlanine transaminase (ALT) is an enzyme found in the highest amounts in the liver. Injury to the liver results in release of the substance into the blood.This article discusses the test to measure the amount of ALT in the blood.Alternative NamesSGPT; Serum glutamate pyruvate transaminase; Alanine transaminase; Alanine aminotransferasaHow the test is performedBlood is typically drawn from a vein, usually from the inside of the elbow or the back of the hand. The site is cleaned with germ-killing medicine (antiseptic). The health care provider wraps an elastic band around the upper arm to apply pressure to the area and make the vein swell with blood.Next, the health care provider gently inserts a needle into the vein. The blood collects into an airtight vial or tube attached to the needle. The elastic band is removed from your arm.Once the blood has been collected, the needle is removed, and the puncture site is covered to stop any bleeding.In infants or young children, a sharp tool called a lancet may be used to puncture the skin and make it bleed. The blood collects into a small glass tube called a pipette, or onto a slide or test strip. A bandage may be placed over the area if there is any bleeding.How the test will feelWhen the needle is inserted to draw blood, some people feel moderate pain, while others feel only a prick or stinging sensation. Afterward, there may be some throbbing.Why the test is performedThis test is used to determine if a patient has liver damage.Normal ValuesNormal range can vary according to a number of factors, including age and gender. Normal value ranges may also vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.What abnormal results meanAn increase in ALT levels may be due to:Acute pancreatitisCeliac diseaseCirrhosisDeath of liver tissue (liver necrosis)Hepatitis(viral, autoimmune)Hereditary hemochromatosisInfectious mononucleosisLack of blood flow to the liver (liver ischemia)Liver diseaseLiver tumorUse of drugs that are poisonous to the liverWhat the risks areThere is very little risk involved with having your blood taken. Veins and arteries vary in size from one patient to another and from one side of the body to the other. Taking blood from some people may be more difficult than from others.Other risks associated with having blood drawn are slight but may include:Excessive bleedingFainting or feeling light-headedHematoma (blood accumulating under the skin)Infection (a slight risk any time the skin is broken)
