Expert:
R.R. Jha
replied 2 years ago.
1)
sin(804 degrees) = 0.9945
cos(804 degrees) = 0.1045
tan(804 degrees) = 9.5144
2)
sin(3*pi/4) = 0.7071
cos(3*pi/4) = 0.7071
tan(3*pi/4) = 1
3)
sin(10*pi/3) = 0.866
cos(10*pi/3) = 0.5
tan(10*pi/3) = 1.7321
4) It's same as part (3). Let me know if it's different.
Please rate the answer.

Can you show your work without using a calculator
Expert:
R.R. Jha
replied 2 years ago.
For part(1), we need a calculator.
In part(2), we've 3pi/4 = pi  pi/4. So,
sin(3pi/4) = sin(pi  pi/4) = sin(pi/4) = 1/sqrt(2) = 0.7071
cos(3pi/4) = cos(pi  pi/4) = cos(pi/4) = 1/sqrt(2) = 0.7071
tan(3pi/4) = tan(pi  pi/4) = tan(pi/4) = 1
In part(3) we've 10pi/3 = 3pi + pi/3. So,
sin(10pi/3) = sin(3pi + pi/3) = sin(pi/3) = sqrt(3) /2 = 0.866
cos(10pi/3) = cos(3pi + pi/3) = cos(pi/3) = 1/2 = 0.5
tan(10pi/3) = tan(3pi + pi/3) = tan(pi/3) = sqrt(3) = 1.7321
Hope that helps. Let me know if you still have any question about it.
Please rate the answer.
