replied 3 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 3 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.

Received it. Could you please split the question as it's a long one? You may then create new question for each part. Just add 'RRJha' at the start of your new question and I'll receive it.

I'll post two answers here. First answer would have solution to question 1 to 15. After you rate that answer, I'll work out question 15 to 29 and post second answer. You'd rate the second answer again paying same amount. Let me know if that's clear and you agree.
