No problem! Let's go through the questions together: 1. Find the exact value of sin(π/3). - The sine of π/3 (which is 60 degrees) is √3/2. 2. Solve for x: cos(x) = 0.5, where 0 < x < 2π. - To find the angle whose cosine is 0.5, you can use the inverse cosine function (cos⁻¹). So, x = cos⁻¹(0.5). - On most calculators, cos⁻¹(0.5) = π/3 or 60 degrees. 3. If tan(θ) = √3, find the value of θ in radians. - To find θ, use the inverse tangent function (tan⁻¹). So, θ = tan⁻¹(√3). - On most calculators, tan⁻¹(√3) = π/3 radians or 60 degrees. 4. Determine the period of the function y = 2sin(3x). Pls teach me how to solve with calculator

When solving trigonometry, is more recommended you put the calculator in radian mode. Degree mode doesn't work in most cases especially when pi (π) is involved.

Master class, it has really helped me.
Thanks alot
I found this really helpful
i thought i knew how to use my calculator all this while... thank you so much ...am beginning to love math once again....
You are welcome. Feel free to check the playlist for more calculator technique videos.
Helpful thanks
Thank you bro I need more

Pls ur solutions,pls why didn't u change it to radian but this tym around in degrees
When solving trigonometry, is more recommended you put the calculator in radian mode. Degree mode doesn't work in most cases especially when pi (π) is involved.
I'm very, very interested
You too good brother ❤️😊
Bro you are a calculator wizard
So interesting
Superb
Bro you are a wizard
Thanks a lot
Thank you Sir. Pls what if the angles are not obtuse, if they are acute.
Do you mean if the angles are obtuse instead of acute,? Because the example I used is when the angle is acute.
@@eaglesclass yeah if the angles are obtuse or if it falls in the 3rd or 4th quadrants
It could have the same approach as solution. I haven't actually solved such example before.
@@eaglesclass Using that same method, it gives wrong answers
Alright. I would have loved to see such question and try it out my self.
Please when am I to save the mode with degree or radius

@@eaglesclass I understand thank you
Sharp 😂
