Evaluate the sine cosine and tangent of 1.)-804degrees 2.)3pi/4 3.)10pi/3 4.)10pi/3
Expert:  R.R. Jha replied 1 year 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.

Can you show your work without using a calculator
Expert:  R.R. Jha replied 1 year 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.

Expert:  R.R. Jha replied 1 year ago.
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.
Customer: replied 1 year ago.
You have until tommorow morning to finish it sir
Expert:  R.R. Jha replied 1 year ago.
These are a lot of questions. Could you break them in two separate questions? If creating a new questions, just add 'RRJha' at the start to send them directly to me.


Thanks
Customer: replied 1 year ago.
Did you solve any of the questions
Expert:  R.R. Jha replied 1 year ago.
I am waiting for your response to my previous query. Let me know and I'd start working on it soon after.
Customer: replied 1 year ago.
I am not sure how to do that
Expert:  R.R. Jha replied 1 year ago.
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.

Thanks
Customer: replied 1 year ago.

Expert:  R.R. Jha replied 1 year ago.
Ok, I'll post the first one soon.
