[mehbhg]

..good explanation ..i really liked your way of teaching..thank alot !

I don't want to use calculator to find the value of tantheta

[NewtonParazo]

if the inclination is negative should we still add 180 degrees to it?

[nanu]

using this for minecraft map coordinates, probably the only person though :frown:

[parthsharma]

oo yes !! thanks a lot sir !!! your teaching style is awesome!!!

[richarde.]

Sir I think it's not allowed to cancel tan^-1 tan. We only apply identity for this operation. Thank u!

[BB-sejp]

how do u know how or where that horizontal comes from

[nightcrawler]

Thank you, really helpful.
My math problem left me with 5 brain cells which are currently thinking about fortnite.

[michamichalik]

What if i calculate further income for very big company and my linear function is y=106491, 03x+2471060. How to calculate an angle for this function. Everyone shows a examples with (m) very small help

[HarshKumar-jeyp]

If I did not have mario I would be done with math class my teacher is so bad

[snow-ydxs]

How do you input this in your calculator, please help me some one im suffering, when i input tan of -3/2 im getting some 0.1128362481 type number, idk how to put inverse of tan theta in the calc

[maximgorki]

In A the slope is -3/2, down 3 over 2 ?

[ratchprekkas]

Firstly, why is the video cut off at the end? And secondly mate, u gotta show us how to do it on the calculator.
