Question

Please help with this?
Solve the equation on the interval [0,2π)

sin θ cos θ=-1/2

Answer 1

So, for this you need to find the instances on the unit circle where Cos*Sin=-1/2

Answer 2

So you need to look for where \[\sqrt{2}/2*-\sqrt{2}/2\] and vice versa. This locations are at 3pi/4 and 7pi/4

Answer 3

Sooooo... i think you have two answers for this one.

Answer 4

ok that works. the answers are 3pi/4 and 7pi/4 then right? the work made sense

Answer 5

Yuppy

Answer 6

thanks!

Answer 7

You're welcome! Again! haha
