Cosine Law & Sine Law To Solve Vector Problems

[@anaperic8549]

Some of these comments are so rude. Thank you for taking the time to make this video.

[@krovely8649]

you are literally a life saver, you explained them thoroughly in a easy to understand way;; thank you so much!

Great video, but please, oh my gosh, drink some water! It's torture listening to this through headphones!

To get 24 on the calculator you press the sin-1 button then (0.3998) which = 23.56, round to 1.d.p = 24.

why do we use the inverse of sine to gain the angle instead of the inverse of tan in this question?

[@ammarchen8850]

thank you so much bro. it helped a lot. I was getting stuck on why the tail to tail question used +2ab on the law of cosines instead of -2ab.

[@dawin3478]

Wow thank this really helped me 😁

[@jacinthbondoc8166]

I'm cnfused where yu gt 24. help

[@pushforyellow]

Me too

[@deadpoolfrancis4527]

@@pushforyellow well he was wrong 92 x sin 140 divided by 148 is actually equal to 0.3996 i calculate it in the calculator many times..

[@mridulmath29]

@@deadpoolfrancis4527 that wont make that big of a difference, you then do whatever 92 x sin 140 / 148 is and then take arcsin which is inverse sin also known as sin^-1 on your calculator

[@jellyandme]

How did he get to 24? He's viewing the result as 'degrees, minutes, seconds' On my calculator, (HiPER Calculator for android), I press the 'more' button in the top right of the screen to view 'calculation details', this shows the result in various forms such as: Decimal value, scientific format, engineering format, Division with remainders' and at the bottom, 'Degrees, minutes and seconds'.

[@haileylauren2919]

how did 140 become negative ?

[@doomsfn.2145]

Sorry I'm 7 years late but it's because of the quadrant it is in, look up the CAST rule on KZbin for a deeper dive

[@brandonsayles1760]

Excellent video. Thank you.

[@stoopokwudiri8558]

How do you mean 140 is in negative range

[@projectonly6229]

how did the answer inside the parentheses becomes negative? at 5:10

[@projectonly6229]

I get it! It is the Quadrants in Cartesian plane, it lies on the 2nd quadrant so it is negative.

[@amarachiogbonna4750]

Pls, how did you get 148 as R. Because it's not giving me 148 but 113.

[@adelbelaifa5492]

Are we allowed to keep a vector sign on R when we talk about its magnitude? thank you!

i thought it was head to tail ... you have head to head in the video

How did you get the 24 degrees and 56 degrees???

Greetings, are you interested in learning about and living for the saviour Jesus who can save your soul from Eternal Hell torment on Judgment day? If not don't read further. Are we the people still putting our trust in temporary things such as money, riches, pleasures of this world, politicians ect which cannot save us from Hell torment on Judgment day? Now is the time to put our trust instead on the eternal God which never dies rather than on temporary money and riches which get old and perish? Are we interested in living fully for our creator rather than being deceived and serving ourselves as our own god? If me and you aren't and want to continue putting our trust in perishable items and riches that cannot save us from Hell on Judgment day please let us not read any further. Originally man lived in pure happiness with God in Paradise but we sinned by disobeying God by eating fruit from the forbidden tree, because of this we were thrown out of Paradise and onto this earth, as we stubbornly found pleasure in eating from the forbidden tree although there were better trees to eat from in the Garden of Eden. God loves us so much that he made a way for us to enter back into paradise by sending his only son Jesus to die for our sins so that he can give us eternal life and save us from death and eternal punishment in Hell. Here is a pray that you and others can say to receive Jesus Christ as your Lord and saviour. Father in Heaven I receive your son Jesus as my Lord and saviour, I confess my sins and I ask you to forgive me for all my sins, wash and cleanse me and everything pertaining to me with the blood of your son Jesus and wash away all my spots, blemishes and wrinkles with the blood of your son Jesus. Father God in Heaven fill me with your Holy spirit every moment of my life and give me infinite oil for my spiritual lamps. I forgive and release all those who have done me wrong and I ask you to bless them and write my name permanently in the lambs book of life in Heaven in Jesus name I pray amen. Here is another pray to break curses and bind demons in our lives. Father God in Heaven I break and loose myself and my family from all curses going all the way back to Adam and Eve and I bind every demon and demonic influence in my life and in my family life permanently in Jesus name. I command all demons in my life and in my family life and those around me to leave and never return in Jesus name. Father God send your legions of Angels to fight for me until the end and send your ministering angels to keep ministering to me and always guide and protect me from all evil, I command Satan to get thee behind me and all of Gods creatures in Jesus name I pray amen. Pray always and study the KJV Bible to know more about Jesus and God's plan for our lives. Live a fully obedient life to God every moment of your life, no matter what Satan may throw against us continue to obey God's voice rather than Satan. Jesus bless you. Please pass on this message.
