Yes, have made a video on coordinate geometry...you may check it out...hope you will find it helpful... th-cam.com/video/c6nlyG7bkfM/w-d-xo.htmlsi=KqzANvmy4nMpxhT4 If you have any doubts,pls let me know...👍👍
There are some keywords you can search for ... usually in LCM questions...you will be asked to find minimum amount or number of something....you can get many answers for the question,but what is the minimum answer? That is the LCM or lowest common multiple... Whereas, for HCF questions,you will be asked the maximum amount of something....there are again many answers possible,but what is the largest possible value ?that is highest common factor.....these are some rough ideas to help us identify whether it's HCF or LCM ... pls let me know if you have any questions....
@@EnjoyMath How do we figure out what to find in this question: In a seminar, the number of participants in Hindi, English and Mathematics are 60, 84 and 108, respectively. Find the minimum number of rooms required if in each room the same numbers of participants are to be seated and all of them being in the same subject. Since this question has the word “minimum” the first thought goes towards finding the LCM but when you look at the solution, we have to find the HCF. How do we understand such questions?
@DhanviSood yes this is a tricky question.... Because when they ask minimum number Of rooms, it means we need to put maximum number of students in each room... That's when we get minimum number of rooms... Suppose we decide to keep 6 students per room also, it will be fine, but then we would need 32 rooms!! So to minimise the rooms, we need to maximize the number of students per room... So to find maximum of students, we take hcf of students...so yes, we cannot directly take the question at its face value... We need to track what they are actually asking for.. Then use the minimum and maximum keywords.any doubts? Pls let me know...
excellent explanation :) thanks mam.
Thank you so much for the wonderful comment.... really happy that you found the video useful!!😊😊😊👍👍
Great step-by-step explanation on proving trigonometric identities! Perfect for building confidence in solving these types of questions.
Thank you so much for the wonderful comment.... really happy that you found the video useful... really motivating words!!😊😊😊👍👍👍
Thank you ma'am very much 😊
Ma'am I have one more doubt
Prove that: (1+tan^2A)+(1+1/tan^2A)=1/sin^2A-sin^4A.
Most welcome!! Very happy to be of help!!😊😊👍👍
Will try my best...👍👍
Thanks you mamm
Most welcome!! Very glad that you found the video useful!!😊😊👍👍
Mam plzz teach cooperative geometry....
Mainly about where to use section formula, k formula, and mid point formula🙏

Ok sure mam
How do we figure out when to find LCM or HCF in word problems? Are there any tricks?
