Good evening/ morning sir. Firstly i want to thank you for this simple yet very helpful explanation. And lastly, i have a doubt that what if we don't know the value of (cos^-1)(-2/5√5)
This is because of change of subject formula. We are looking to find the value of θ and not cos θ. So to get rid of the cos on the left hand, we multiply both sides by the inverse of cos (cos₋₁). The cos on the left hand will be cancelled out by the cos inverse and then we are left with θ = cos₋₁(everything on the right side). Hope I've been able to help
hello what if the vectors are like a= 3i + 2j b= i + 5k (examples made up in my head) if i will find a dot b will it be (3×1)+(2×0)+(0×5) or (3×1)+2+5 ???
Now crystal clear sir , i am struggling this topics for months, you made it simple sir thank you sir 🎉

You use a calculator for this
Normaly your school will know this.they will set question like that so that you get values uk
Or just leave it in cos inverse form
This just helped me figure out a problem I have been confused on for weeks! Thank you so much for your help!
Easy to understand and well explained
Simple an straight to understand 👏👏👏 I love it

sir you are amazing at explaning🎉🎉👏👏👏👏👏👏👏
i like your nigerian accent sir
God bless you man ❤
Thank u so much ❤️I had an assignment due tommorrow
Thank you sir
Thank you sir ❤
Do we have to put modulus and then 90 minus the angle if we want to find acute.
Great 👌
Well explainer ❤
Well explained
Thanks
Congratulations you have assisted me
Sir i will rest in peace by this speed of learning 😂😂😂😂😂
I have 45 seconds in classs to doo
Well explained sir, kindly help me with these two questions:Factorise x^3-4x^2-3x+18 and prove that sinx/1+cosx+1+Cosx/sinx=2/sinx please
Inbox I send answers to your E-mail.
Thanks sir for the wonderful lecture .My question is why are we using COS-1 to multiply the figures?

find the angle between vectors ā=5i+3j-2k and b=-i+4j+k
Sir Pls help with this I’m confused or anyone
Use Dot product
Nice
Tq very .ver.much.lovely..sir..well.explained
Thanks
Thanks!!!
very helpful for my physics course! thank you fine sir!
You're very welcome!
Perfect👏
Thanks sir....❤
Thank you
hello what if the vectors are like
a= 3i + 2j
b= i + 5k
(examples made up in my head)
if i will find a dot b will it be
(3×1)+(2×0)+(0×5) or (3×1)+2+5 ???
i was thinking that itll be multiplied to 0 since there was no variable given
