What does exact form mean in mathematics?
The exact form usually means that we have some irrationals included in the answer. Thus we want to leave the answer in its original form….or express the answer as some multiple of pi, etc……
What is the exact simplified form?
A fraction is in its simplest form when the top and bottom cannot be any smaller, while still being a whole number. Example: 2/4 can be reduced to 1/2. To simplify a fraction: Divide the top and bottom by the largest number that exactly divides both numbers (they must be whole numbers).
What is meant by exact answer?
This means that you leave your answer as a fraction or radix (the square root symbol) instead of a decimal answer.
What is an exact value?

what is sin
Viewed from a vertex with an angle, sin(θ) is the ratio of the side opposite the hypotenuse, while cos(θ) is the ratio of the side adjacent to the hypotenuse.
What is sin equal to?
Always, always, the sine of an angle is equal to the opposite side divided by the hypotenuse (opp/hyp in the diagram). The cosine is equal to the adjacent side divided by the hypotenuse (adj/hyp). (1) Remember: sine = (opposite side) / hypotenuse. Cosine = (adjacent side) / hypotenuse.
Who is the father of trigonometry?

Why is it called trigonometry?
The word trigonometry comes from the Greek words triangulation (“triangle”) and metron (“to measure”).

How is trigonometry used today?
Trigonometry can be used for the roof of a house, for tilting the roof (in the case of single individual bungalows) and for the height of the ceiling in buildings, etc. It is used in the naval and aviation industries. It is used in cartography (creation of maps). Also trigonometry has its applications in satellite systems.
How do doctors use trigonometry?
Trigonometry is used in orthopedics to detect the deviation of a vertebra in degrees and to know whether nerves are damaged. It is also used to mold prosthetic arms and legs, which conform to measurement to allow operation closer to the parent member.
How do pilots use trigonometry?
Trigonometry allows pilots and flight engineers to account for their speed, velocity, angle of climb or descent as well as other external factors such as wind speed and direction. To do this, they use triangles and other structures made of vectors.
How do nurses use trigonometry?
Getting an associate’s degree is a shorter and more clinical-based approach to becoming a nurse. During CAT and MRI scans, nurses also interpret graphs, may use triggers to locate tumors, and determine heart rate. ,
Can I become a nurse if I am bad in maths?
Mathematics is essential for nursing so depending on your area of expertise in nursing, you may need to use basic arithmetic and algebra on a daily basis. If you had a bad experience or struggled with math as a child, you’ve probably done a good job of avoiding it in your life. But nursing school is not a high school.
What math do nurses use?
According to Boyd (ND), “Nurses regularly use additions, fractions, ratios, and algebraic equations each workday to administer the correct amount of medication to their patients or to monitor changes in their health” (para. 1). .
Can nurses use calculators?
Do nurses use dosing and counting at work? Surprisingly, yes! I use dosing and counting frequently at work, and many other nurses I work with do as well. In fact, I will tell you about 3 situations when dosage and calculation skills are used at work.
What was the toughest class in nursing school?
toughest nursing school classes
- Pathophysiology. In this course, students learn how different bodily systems work and how diseases or injuries affect these systems.
- Medical Surgical 1 (also known as Adult Health 1)
- Evidence based work.
How do nurses calculate medications?
Determine what units your medicine is measured in (units/hour, mg/hour, or mcg/kg/minute). If your calculation is based on weight, then know the patient’s weight in kg. Use the universal formula below and then divide the patient’s weight in kg by the patient’s weight to arrive at your final answer, mcg/kg/min.
How do you calculate dosage?
how to calculate drug dosage
- Determine the dosage of the medicine.
- Weigh yourself.
- Multiply these two values to get the drug dose in milligrams: 2 * 80 = 160 milligrams.
- What if your medicine is liquid?
- Divide the dose by the drug concentration to get the liquid dose: 160/2 = 80 ml.
What is drop factor?
Drop Factor = Number of drops to make one milliliter of fluid. There are two common sizes: 20 drops per milliliter (usually for clear liquids) 15 drops per milliliter (usually for thicker substances, such as blood).
How do you convert milligram to ml nursing?
So, 1 mg is found in 0.5 ml of solution. So, if 0.5 ml contains 1 mg of active drug, we can multiply 0.5 ml of solution by five (as we want 5 mg of drug) to get our answer. Multiplying 0.5 by five gives 2.5 milliliters.
How does weight affect the effectiveness of the drug?
Changes in body weight can affect the amount of medicine you take and how long it stays in your body. The circulatory system may slow down, which can affect how fast the liver and kidneys get the drugs.
Does body weight affect drug absorption?
Obesity also has an effect on gastric emptying and gut permeability, meaning that drugs are absorbed at different rates than normal. The penetration of the drug into tissue is also affected, which means that higher doses may be needed to reach effective concentrations.
What is an ideal body weight?
It measures a person’s weight in relation to their height. According to the National Institutes of Health (NIH): A BMI of less than 18.5 means a person is underweight. A BMI between 18.5 and 24.9 is ideal. A BMI between 25 and 29.9 is considered overweight.
