9. Why are karyotypes useful diagrams? What can they show you about an organism? 10. Organisms have different numbers of chromosomes. Fill in the chart below about 5 different organisms. Species # of homologous # of chromosomes in # of chromosomes in diploid cells chromosome pairs in haploid cells diploid cells (2n) (n) Humans 46 23 pairs Bat 44 Monkey 21 pairs Camel 35 Dog 78 1 1. The number of chromosomes during meiosis is incredibly important. Why is that? Exercise 2.10.7: The Unit Circle In this program we are going to practice using the Math class by computing some important values on the unit circle. Using the angles 0, PI/2, and PI, print out the angle, the cosine of the angle, and the sine of the angle. Your output should look like this: Radians: (cos, sin) 0.0: 1.0, 0.0 1.5707963267948966: 0.0, 1.0 3.141592653589793: -1.0, 0.0 Hints: You'll need to use the Math.sin, Math.cos methods and the Math.PI constant! You can round a decimal to 2 decimal places by multiplying by 100, rounding to the nearest int using Math.round, and then dividing by 100. You will need to round the sine and cosine values. Here's an example: double angle = Math.PI/4; double cosine = Math.cos(angle); // 0.707106781 cosine = cosine * 100; // 70.7106781 cosine = Math.round(cosine); // 71.0 cosine = cosine / 100.0; // 0.71 // Or put it all on one line: cosine = Math.round(cosine * 100) / 100.0; Some Math Background The Java methods need the angles to be in radians, rather than degrees. PI/2 radians is equal to 90 degrees. PI radians is equal to 180 degrees. That's why we're using multiples of PI in this exercise. UnitCircle.java public class UnitCircle { public static void main(String[] args) { System.out.println("Radians: (cos, sin)"); // Put your code here! } }
