I think he just confused himself with the second dot. If you use that one you can see you can still do COS. So he just worked out the wrong thing. He is correctly incorrect. Jokes aside,everyone makes mistakes
Don't put the whole thing in the calculator first, since there's a plus sign between the sums, first to the one on the left and get it answer, same goes for right , and then you finalise, just like how he did, when he first wrote -3+4
that would be true if we were told the angle is cos(theta) and that would make it -4/5 but since the question raised said its cos(90 deg - theta) that makes it a new angle, lets call this angle dot, if you stand at dot and are told to find cos that would be adj/hyp or -3/5 . Hope this helps
that would be true if we were told the angle is cos(theta) and that would make it -4/5 but since the question raised said its 5cos(90 deg - theta) that makes it a new angle, lets call this angle dot, if you stand at dot and are told to find cos that would be adj/hyp or -3/5 . Hope this helps

Can you please help with Grade 10 Trigonometry Angles of elevation and depression
Honestly your the best teacher
P,LEASE CAN YOU HELP US WITH PHYSICS GR 10
Yess
Yoh yes please
YESSSS PLEASE KEVIN, HELP US WITH GRADE 10 PHYS/CHEM
he does why do you think he’s name is Kevin maths SCIENCE he does physics just search your topic then at the end science Kevin maths science
Dude ngl physics is ez
for 1.2 why is "cot" not its reciprocal which is cot=1/tan theta
Thank you so much😢.
My math teachers told me that cot was 1 over tan theta. That really confused me, so thank you sir
It is bro
MR kev could you please do an Electrostatics revision
Thank you kelvin
Angles of elevation and depression
I think u made a mistake
Our answer must give us 0 not 1
-4(adj)
-3(opp)
Your 100% right
Okay
No it's 1
3(-4/3) = 4
Sir you used the opposite as the adjacent of which is incorrect
I noticed aswell
Honestly thank you so much for this🙏
kevin can is use the fx 82ms calculator to sketch the trig graph?
I think mr Kevin made a small mistake in question 1.2,he used SOH in place of CAH and the answer is incorrect

Jokes aside,everyone makes mistakes
He did
The final answer is 8 for 1.2
I think you guys made a common mistake.
For 1.2
My final answer was -7/4
Where did u get the 5 from?
Very helpful
How do you get the answer without a calculator because in the question it asks you to solve without the use of a calculator
Don't put the whole thing in the calculator first, since there's a plus sign between the sums, first to the one on the left and get it answer, same goes for right , and then you finalise, just like how he did, when he first wrote
-3+4
@lisancitha2865 thank you
Were do you get your past papers 😢
google
Grade 10 chemistry plz.🥺
wait dont you have to make the exponents negative bc their x and y values are negative
Bros lost 💀
The negatives cancel boss.
But then i don't understand why we have -3/5 as cos whereas cos=A/H it's suppose to be -4/5
that would be true if we were told the angle is cos(theta) and that would make it -4/5 but since the question raised said its cos(90 deg - theta) that makes it a new angle, lets call this angle dot, if you stand at dot and are told to find cos that would be adj/hyp or -3/5 . Hope this helps
How much do want so u can be hired at my school
Greatest greatest greatest greatest greatest greatest greatest greatest greatest greatest greatest greatest greatest greatest greatest 😂😂😂😂😂😂
4:17 5(-4/5) why -3
that would be true if we were told the angle is cos(theta) and that would make it -4/5 but since the question raised said its 5cos(90 deg - theta) that makes it a new angle, lets call this angle dot, if you stand at dot and are told to find cos that would be adj/hyp or -3/5 . Hope this helps
Oi little mistake its -4/5 for 5cos(90- peter)
