Oh, I'm sorry, but the give function is y=5cot(-2x)

Thank You Steve. I now understand it :)

Hi Damon, Thanks for finding the time of day to help me. However, I'm not as smart as you are and I'm sure you'll expect me to know the answer. I've tried putting in -5/sqrt74*-3/sqrt34 +7/sqrt74*5/sqrt34 in my calculator, but instead it comes out with a really ugly number and I'm sure it's the wrong answer. So, if you will be so kind to help me out here will be nice. Thank you. I have few more of questions like this to solve and I'm not even close to finding this answer.

Hi Steve, Please accept my apologies. My initial question is wrong. They want me to find cos(α−β), not sine(α−β). I really am sorry. I had the same answer as 5/radical629, but when I typed it in my h/w answer box, it kept saying the answer was wrong. So I was wondering why. Then, I re-read the question. Sorry once again, it was a stupid mistake. I re-read my question after typing it, but I didn't see my error. So please help me find cos(α−β) of the question. THANK YOU SOO MUCH.

THANK YOU GUYS SOOO MUCH, GOD BLESS.

I love you Reiny lol thank you sooo much. Thank you steve.

2x-6=3x+1-x-7 Step 1: 2x-6=3x-6-x (how i got -6? 1-7 =-6) step 2: 2x-6=2x-6 (how i got 2x? 3x-x=2x; there's an imaginary 1 in front of x) step 3: Take ONLY the 6 on the left side of the equation, and add it to the 6 on the right side of the equation. So it will look like this, 2x-6+6=2x-6+6, therefore you'll get 2x=2x+0 step 2: Take the 2x on the right side of the equation and subtract it from the 2 in the left side of the equation. You'll get x=0 as your final answer. So your answer is 0. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ To check if 0 is the right answer. Plug in zero in every occurrence of x. So, 2(0)-6=3(0)+1-0-7. The left side of the equation will give u 0 and the right side of the equation will give you 0.

Thank you Reiny

I believe it's 16

THANK YOU Scott. I did the reverse sin to get .7076 in my calculator. How did you get 2.4340? Sorry if this question should be obvious to me.

Hi Reiny, those are the choices they gave me. Apparently, I have to pick the right choice and fill it out. Below is the instruction it gave me when I filled out the wrong one. "First, isolate the trigonometric function on one side of the equation. Next determine the quadrants in which the terminal side of the argument of the function lies or determine the axis on which the terminal side of the argument of the function lies. If the terminal side of the argument lies within a quadrant, then determine the reference angle and the​ value(s) of the argument on the interval ​[0,2π​). If the terminal side of the argument of the function lies along an​ axis, then determine the angle associated with it on the interval ​[0,2π​). ​Finally, use the period of the given function to determine the general solution. Use the most concise way to describe the general solution by making sure that the listed equations do not produce the exact same solutions.​ Also, ensure that none of the general solutions that have been entered can be consolidated into a fewer number of general solutions.​"
