Bro you are a calculator wizard

[@excelachara4594]

Thanks alot I found this really helpful

[@McDavid-bj9yx]

Bro you are a wizard

[@emmanuelasasey1289]

Master class, it has really helped me.

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.

i thought i knew how to use my calculator all this while... thank you so much ...am beginning to love math once again....

[@eaglesclass]

You are welcome. Feel free to check the playlist for more calculator technique videos.

[@SscWallahGuddu]

Superb

[@oladapoazixx6981]

It really cool 😎

[@mercyoderinwale1651]

You too good brother ❤️😊

[@francisoppong2503]

Pls ur solutions,pls why didn't u change it to radian but this tym around in degrees

[@eaglesclass]

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.

[@davidwadata6178]

So interesting

[@Humphrey_x]

Thanks a lot

[@Azeez_Mansur]

Thank you Sir. Pls what if the angles are not obtuse, if they are acute.

[@eaglesclass]

Do you mean if the angles are obtuse instead of acute,? Because the example I used is when the angle is acute.

[@Azeez_Mansur]

@@eaglesclass yeah if the angles are obtuse or if it falls in the 3rd or 4th quadrants

[@eaglesclass]

It could have the same approach as solution. I haven't actually solved such example before.

[@Azeez_Mansur]

@@eaglesclass Using that same method, it gives wrong answers

[@eaglesclass]

Alright. I would have loved to see such question and try it out my self.

[@user-nx1hb2ve4m]

Please when am I to save the mode with degree or radius

[@eaglesclass]

When solving trigonometry, is more recommended you put the calculator in radian.

[@user-nx1hb2ve4m]

@@eaglesclass I understand thank you
