Sorry, I got confused with another question I was doing. The question was
Find the general solution solution of the equation sin2x=-√3/2 and use it to find all the solutions for 0°≤x≤720°. ...NOT 360 as I had above.
The solutions say that 120°,150°,300° and 330° but I think that the solutions...
Hi,
Thank you. You may be able to help with one other question.
Find the general solution solution of the equation sin2x=-√3/2 and use it to find all the solutions for 0°≤x≤360°.
The solutions say that the answers are 120°,150°,300°,330°. I think that the solution set should be 0°≤2x≤360° for...
Hi,
Believe it or not I am a teacher ! How embarrassing haha!
We are having a debate about the solution to this question!
I do not understand why the solution divides by 2 if you use the average value formula in integration to find average speed. If you substitute in values between 0 and 1...
Hello,
I was wondering if someone out there could help me. The question:
The speed, v metres per second, of a particle is given as v=8sin2t+3cos2t
where t is in seconds.
i) Find the total distance traveled in the time interval 0≤t≤1
ii) Find the average speed over this time interval.
