Distance Between 2 Ships (Angle of Depression)

[@maccliff2115]

that side note of telling us to make sure we are in degree mode on our calculator was SUPER HELPFUL !!! Thank you for posting this. It helped me greatly. Thank you.

[@MariosMathTutoring]

You're welcome! I'm glad you found the video helpful. 👍

[@tambuwalmathsclass]

Great. But for the sake of beginners, stop being, stop rushing fast. 👍

[@Abdi._.M3]

I was just doing my home work and i found you, and you have no idea of how I like it. Thanks very much!!!

[@whatdatechnodogedoin]

You sir, is a life saver.

[@ポッド-j6s]

sir u really out here saving lives

[@ecoobagg6182]

2:58 : where did u get the value of “D”???

[@charityharrell4719]

it’s the value of tan10°(d) so d doesn’t really have value yet

[@IOwnKazakhstan]

had a question that had me absolutely lost for a little bit but eventually I got it. A plane is at an altitude of 400m, the pilot looks down at a landmark at an angle of depression of 1.5 degrees, two minutes later, the angle of depression was 5 degrees. The question asked to find the speed of the plane in km/h. To me that sounded like a "there were 4 boys and 6 apples, how many seals were at the zoo" type of impossible question. For a solid 5 minutes I stared at the question thinking "what the actual f*ck am I meant to do" and then it clicked lol. It's 321.1km/h I believe

Brilliant video, I needed this for my 9th grade trig exam.

[@nomogi]

thank you! what about if the boats are in two opposite sides?

[@sionealofi167]

Hi sir, could you please explain how you extracted the value of D from the calculator?

[@Streamer_Plug]

tan(10)

[@matematicacomdemoclis]

Great video. Where did this problem you solved come from?

[@tambuwalmathsclass]

Just assuming

[@scottnicholson9651]

This was great, Thank You!

[@KholiswaGobeni]

Thank you so much sir!!😊

[@MariosMathTutoring]

Most welcome 😊

Thanks for the teaching sir

mario u got me full marks on my hw ty pookie

[@Chadmarine]

I'm putting 37320.5tan(10) and I get 24197.2 in 2:49. what am I doing wrong?

[@nickaguirre6317]

Thank you for the video Mario

[@nokwandadlamini5361]

great video, really helped

[@sarasaavedra8827]

Hi Mario. I was wondering if you could help with some math homework. Q: A lifeguard spots a swimmer in the lake at an angle of depression of 45°. He spots a sailboat, further out, at an angle of depression of 26°. If the lifeguard is 36.5 dm away from the swimmer and 84.7 dm away from the sailboat, how far is the swimmer from the sailboat? The difference between your question and mine is I don't know the height of where the lifeguard is sitting. Would I instead use cosine to find x?

[@sxrge7349]

Sorry no

[@chai2131]

thank you so much sir!

[@gabrielasoler8400]

Hello Mario! Could you please give some techniques to add or subtract numbers mentally faster? What is intereresting is that I tend to multiply and divide faster mentally 😄. Thank you!

[@MariosMathTutoring]

Hi Gabriella, good question! I don’t have a video on that topic yet but I’m glad you are looking at upleveling your skills!

[@gabrielasoler8400]

@@MariosMathTutoring Thank you!!! Yes, I am looking for that! You may call me Gabby!

[@Lala-p3d5p]

Thank you so much omg !!!

Welcome!!

Glad you liked the video Yaser!

[@lifewithsara2191]

Hello sir can you please make a video on rational numbers 💖

[@lifewithsara2191]

And their operations💖💖 Thankyou

[@Foreverrulla]

How did find d stop going fast and explain

[@samarthk5434]

Thanks

[@JuliusPalomares]

Sir how to fin the tan 10 x d???

[@rickbman6367]

Why is it so dam hard to find a video with just 2 angles of depression and no sides? Fuck I hate math

[@yurmomsie]

how did you get D? you got 1.76 but didn’t really explain where you got it from?

[@espinosaephraimjoshr.1824]

Same question here

[@mugiwaranoluffy2406]

It's tan(10°) bruh. Try it to your calculator and you'll get the answer

[@creepermods4641]

D represents another variable to make it clear that they don't use same variables.

[@RayDoeksen]

“Solve for d” happens at about 2:50 d is the difference between the sea level distance between the plane and the first ship, and the plane and the second ship. That’s the distance between the ships, in this simplified 2-dimensional problem.

[@Gorillax7223]

Check inside your pants you'll find d

[@Emmiiillyyy]

why are you adding D? Wouldnt distance mean you would subtract d from x?

[@ragnarokk7384]

Hi can u help me with my homework :3 Transform the following to matrices to RREF A=[ 3 2 2 ] -2 0 1 1 -1 0 B= [ 1 2 3 4 ] -2 4 -3 5 3 0 5 -3

[@MariosMathTutoring]

I did a video on the topic here: Row Reduced Echelon Form kzbin.info/www/bejne/r4iyY6mPo5KHjpY

[@Theosphobia]

when i inputted 10000tan(15) i got 2679.491924 ??? i dont know what im doing wrong :(

[@mariobethell3731]

Divide 10,000 by tan 15 (0.267949) = 37,320.5

[@Purposefulartlly]

tan(10) x (37320,5)=6580,6
