Question

Hi! I need to know how to add things like (pi/3)+(pi/2). I have no idea what that type of operation is called, but I need to it to graph sin and cos.

Answer 1

Ignore the pi's

Think of it as 1/3 + 1/2

Answer 2

How would you add those two fractions?

Answer 3

find a common denominator, add the numerators, then simplify if i can

Answer 4

good

Answer 5

So it would basically be 5/6?

Answer 6

Answer 7

1/2 + 1/3 = 5/6

Answer 11

Thank you so much! You just made my life soooooo much easier, both of you

Answer 12

Here's a more detailed break down

pi/2 + pi/3

(3/3)*(pi/2) + (2/2)*(pi/3)

3pi/6 + 2pi/6

(3pi+2pi)/6

5pi/6

But I'm sure you see it by now

Answer 13

Yep, I do, but the breakdown helped any doubts I had. Thank you for taking the time to do that, many people wouldn't, but I really appreciate it.
