Write a java program to read an angle value d in degrees, then it:

a. Prints the equivalant radian value r

b. Prints the values of sin® and cos®

c. Prints the values of log(d) and d5

Example:

Reference: http://download.oracle.com/javase/6/docs/api/java/lang/Math.html

Please enter an angle value (in degrees): 227

The equivalent radian value: 3.961897402027128

sin(3.961897402027128) = -0.7313537016191705

cos(3.961897402027128) = -0.6819983600624986

log(227) = 5.424950017481403

227^5 = 6.02738989907E11
