In Java PLease 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.

Formatting rows and columns is similar to cell formatting. in an openoffice calc spreadsheet, you can format data entered into rows and columns with the of the rows and columns options. you can insert rows and columns into, or delete rows and columns from, a spreadsheet. use the insert or delete rows and columns option on the insert tab. alternatively, select the row or column where you want new rows or columns to appear, right-click, and select insert only row or only column options. you can hide or show rows and columns in a spreadsheet. use the hide or show option on the format tab. for example, to hide a row, first select the row, then choose the insert tab, then select the row option, and then select hide. alternatively, you can select the row or columns, right-click, and select the hide or show option. you can adjust the height of rows and width of columns. select row and then select the height option on the format tab. similarly, select column, then select the width option on the format tab. alternatively, you can hold the mouse on the row and column divider, and drag the double arrow to the position. you can also use the autofit option on the table tab to resize rows and columns.
