Q

When making an estimate for division, which way do we adjust each number (numerator and denominator)? Example?

A

We make a proportional adjustment in the same direction (in multiplication we lower one and try to increase the other)

Q

When making an estimate for multiplication, what should we do if we need to adjust both numbers? Why do we need to keep track of adjustments?

A

If one number is rounded up, it is best to round the other number down slightly to compensate.

Keep track of adjustments and how they impact your final answer.

33
Q

What is the approximate value of sqrt(2) and sqrt(3)?

34
Q

The rules for logarithms follow the same trend for exponents because they are inverse functions. What are the rules for logarithms?

35
Q

Derive the Henderson Hasselbalch from the expression for Ka

A

This is a good one.

36
Q

How do we convert between natural logarithms and common logarithms?

37
Q

What is the quantity of Euler’s number?

38
Q

How do we estimate logarithms using scientific notation?

39
Q

What is a good approximation for this:

40
Q

Approximate this:

41
Q

Approximate what is in the image. Why does that look familiar?

A

Estimating logarithms is used in calculations of pH. We work with negative logarithms and a negative exponent in the case of pH.

46
Q

What is sin cos and tan of 0, 30, 45, 60, and 90°?

Q

MCAT concept check trigonometry 3.1 page 375 question 2

Also, what is sin cos tan of 0,30,45,60,90°?

A

SOH CAH TOA

49
Q

Why is tan of 90° undefined?

A

Because it involves dividing by 0. Tan being sin/cos, and cos(90°) is 0.

50
Q

MCAT concept check trigonometry 3.1 page 375 question 3

True or false. Only angles in right triangles have characteristic values of the trigonometric functions.

A

False. Even though calculating the values of sine, cosine, and tangent, is more complicated in a triangle that does not contain a right angle, all possible angles do you still have characteristic trigonometric values.

51
Q

MCAT concept check trigonometry 3.1 page 375 question 4

At what angle between 0° and 180° does each trigonometric function have a value of 1?

Also. What is sin, cos, and tan, of 0, 30, 45, 60, 90°?

52
Q

What is a direct relationship, what is an inverse relationship?

A

Indirect relationships, increasing one variable proportionately increases the other: as one decreases the other decreases by the same proportion.

In inverse relationships, any increase in one variable is associated with a proportional decrease in the other.

54
Q

Convert 6 hours to minutes. To seconds.

55
Q

Conversion example page 378

A

This was a good exercise in unit conversion and estimation.

56
Q

What are the conversations between F, C, and K.

57
Q

What is normal body temp in F and C? What is a fever designated as? Hypothermia?

58
Q

What is dimensional analysis? How is it helpful?

A

Dimensional analysis is the analysis of a relationship utilizing the units given and desired as the units of the calculated answer must match the units of the answer choices on the MCAT.

Consider given quantity of N/C, and the other in volts. The answer choice for the question are in meters. Even without tempering that E=Vd, we can divide the voltage by the electric field to get meters:

63
Q

MCAT concept check problem solving 10.4 page 381 question 1

how are conversions between metric prefixes accomplished? How would a distance be converted from millimeters to kilometers?

A

Conversion between metric prefixes is accomplished by multiplication or division by the appropriate power of 10.

64
Q

MCAT concept check problem solving 10.4 page 381 question 2

A
