Let's look at the quadrants first...assuming the arguments are in degrees, can you state what range of degrees the 4 quadrants encompass, for ?
I have an idea just wanted to see if I was correct without actually embarrassing myself. Can you answer the first question number 1?
So, in which quadrant is ? And don't worry about embarrassing yourself, there is no shame in asking questions, the only shame is in not asking when you don't know.
Lol ok cool I have no idea when it comes to sin 186... Or which quadrant it would be in.
Which range of values does 186° match? Is it in between 0° and 90°, or in between 90° and 180°, or in between 180° and 270°, or in between 270° and 360°?
Guessing 3rd quadrant 180 and 270
Yes, since 180 < 186 < 270, we know 186° is a quadrant III angle. As such, what can we expect the sign of sin(186°) to be? Will it be negative or positive?
So is that the answer?
Are you instructed to use your calculator to get a decimal approximation or to use identities to obtain an exact answer?
