I want to learn how to find the angels A with:
0, less than or equal, A ,less than or equal to, 2pi that satisfy equations such as these:
sin A = -1 (I got, -90, and 90 degrees)
cos A= 1 (I got, 0)
sin A= 0.4 (I got, 23.5782 and 156.4218 degrees)
cos A= -0.6 (I got, 126.8699, and 233.1301 degrees)
tan A= -2.5 (I got, -68.1986, and 248.1986 degrees)
I am familliar with the process, but the answers I find for each are in degrees, and for these particular types of exercises i want to use radians NOT DEGREES and round the answers to four/ five decimal places.
Can you show me the processes to take to find the answers in radians? THANKS!!
