Angle between a vector and the x-axis (KristaKingMath)

[@ani.g5956]

for finding theta, if you have a casio calculator, you can use the inverse tan function

[@mitalibiswas9251]

Yeah

[@Yash_SG8]

That was too easy! You explained the whole basics of trigonometry too! You're a great teacher for mere beginners. I just wanted some correct explanation because of a *WRONG* explanation by a random reference book to confirm my steps. And I found you. Thanks a lot!

[@alexpierce9165]

You’re a lifesaver. Literally............Thanks

[@kristakingmath]

I'm glad it helped!

[@justinbeaubien4298]

Thank you for making this! You explained it so well!

[@kristakingmath]

+Justin Beaubien You're welcome, I'm glad you liked it!

[@MayBlaze0]

This. Is. Amazing. I don't know why Khan Academy is so much more well-known. Your videos are so much more helpful.

[@kristakingmath]

Thank you so much, I'm so glad it helped!

[@utkarshsingh_0121]

I like your teaching method Love you from INDIA 🇮🇳🇮🇳🇮🇳

[@vanamabhinaytinku6552]

Superb concept

[@cynthiaknox8978]

THANK YOU; you explain things so clearly! Very thorough.

[@kristakingmath]

Aw thanks! Glad I could help!

Very do much,clearly explained.

why is sqrt of 3 not negative? isnt the formula for a vector in the ijk form: i-j+k? so wont that mean that the coefficient of sqrt 3 j be (- sqrt 3)?

[@adedamolaakapo5774]

What is your Y is negative

[@4nkur5ahamusic]

Thank you mam, this was very helpful

[@kristakingmath]

You're welcome, Ankur! I'm so glad it helped! :)

[@stemerlife]

what is the term of I and J

[@minecraftkasuperstar7176]

Thanks very much, helped a lot 😊

[@Tumilson94]

I lost my notes. Thanks this helped so much

[@kristakingmath]

+Ryan Tumilson I'm glad I could help!

[@madcatmascot127]

Could also do something so much quicker by doing tan^-1(sqrt(3))=pi/3 and then to get a degree value multiply by 180/pi = 60 degrees

[@AlteredCreation]

simply doing arctan(sqrt(3)) will give you the value in degrees

[@6Diego1Diego9]

Will you ever do DiffEq?

[@kristakingmath]

I do have some videos on differential equations at the moment, but I hope to go into more detail in the future. :)

[@kingz.a1918]

thanks for the dissertation

[@lovelyjkr]

Thank you soooo muchh

[@kristakingmath]

You're so welcome! I'm happy to help! :D

[@atik8896]

What if i get other value than root of 3 ?

[@hazza2247]

Just do the same stuff but for whatever number u have

[@flagheist]

Thank u ✨

[@kristakingmath]

You’re welcome! :D

[@rogelio321]

Thank you so much! Gained a subscriber :)

[@kristakingmath]

Thanks! :D

[@Ensign_Cthulhu]

a.b = |a| |b| cos theta. Use (1,sqrt(3)) and dot it with (1,0)

[@ayushamahatra71]

Thank You mam . It hepled so much

Find the vector of length 2that makes an angle of/4 with the positive x-axis.

[@deborahokafor203]

Thank you!

[@Shwaggggg]

What if there is a Z component? For example; Find the angle made by the X axis and (1,2,3)

[@hellygaming5392]

Whitley Howe you could use cubic/cuboid diagonal formula

[@icedgodz428]

thank you

Thank you I am from India

Thank you mam

[@kristakingmath]

You're welcome, Kaushal!

[@vietanhnguyen9740]

I understood now

[@kristakingmath]

+Viet Nguyen I'm so glad it made sense!

[@joshy1279]

why don't you just use a calculator rather than that massive circle thing? American maths is so weird.

[@winston2831]

Because you should understand why and how that works. Why isn’t every math problem just solved with a calculator

[@joshy1279]

@@winston2831 dont get me wrong, I understand that, I think what i meant is why is this being taught as the method that is required rather than using a calculator. In our maths class, everything beyond 16 years old is all calculator papers

[@DanielFlores-ls2lj]

Terrible teacher
