I have the question
a) 3sin(2pi/3) + 2tan(5pi/4)
I have to solve it without a calculator, could you explain step by step how you did it? Thanks.
First of all, thank you for taking the time to help me and all, much appreciated.
To my understanding, sin (2pi/3) is pretty much a third of the unit circle located in the 2nd quadrant, then we find the RAA which makes it sin(pi/3), am I correct? Also, I have some problems visualizing the unit circle. Is there any easier way to visualize if you have a question like sin (11pi/6)?
Anyways, continuing with the question
=3sin(pi/3) + 2tan (pi/4)
=3(1/2) + 2(1)
=5/2
Is this correct?
