Problem 3
Give all answers for this problem to 2 significant figures. Convert the following vectors from Cartesian (x,y) to polar (r,θ) form.
a) (4,−6) b) (−5,−1)
Convert the following vectors from polar (r,θ) to Cartesian (x,y) form.
c) (7,165˚) d) (2,250˚)
1. Multiplication or division: keep the same number of significant figures in the product or
quotient as is in the least precise factor.
Examples:
3.1 * 25.6=79.360000...
= 79
6.7/981.0=0.0068297655...
= 0.0068
keep only 2 significant digits
2. Powers or roots: keep the same number of significant figures as in the original number.
Example:
Sqrt(38) 6.164414...
keep only 2 significant digits
= 6.2
(11.6)² = 134.5600000...
= 135
Exercises
3. Addition or subtraction: Round off, to the number of decimal places determined by the
number with the least number of places beyond the decimal point.
Example:
31.5+24.61 +3.28+1.19 +0.762 +0.003 = 61.345
1. 3.9 * 78.9=
= 61.3 (correct result)
2. 32.01 +96.321 +36.98 +0.00023 +28.9=
3. 26.9/98 =
4. 421 0.003 =
