Han derivative se sin cos mein equation bnegi aur wohh mtlb solve krna bhot lengthy hai mujhse toh uske baad solve hi nhi hua😂 meri bhi first approach derivative hi thi kyunki phy ne aisa mind develop krdiya ki min max dikhthe hi differentiate krdo😂😂😂
when you will take derivative and equate it to zero. then after squaring it you will reach a trigonometric equation which will take time to solve. But the solution described in video will solve the question in less time. Derivatives are not always efficient when it comes to "find the maximum or minimum value" type of questions.
haan thora tough toh hai. lekin it is better ki tum kuch cheeze already decide karke chalo about any type of problem. For example jo question video mai hai usmai following methods should come in mind: 1. square kholkar expansion and simplification 2. substitution karke derivatives ka concept use karna 3. distance method (discussed in video) Aise karke tumhe paper mai bhi easy rahega questions solve karna. Hope it helps.
Direct derivative kar sakte hai na? Tho i have practiced this approach.. this type question is in black book .. also i have a demand.. can u make such videos on conic sections and probability plss. Like those untouched concepts which are IIT can ask next year

yes physics mai differentiation sufficient rahta hai. But this is maths yaha observation always wins.
Are derivatives not more effecient?

Ab ye distance wali out of the box baat exam ke bich me click kaise kregi🌬

Sir vaise maine ise click karte hi samjh gaya ki isme distance formula wala approach lena hai
Maine pahle bhi aise 3 se 4 question kiye hai

Actually direct derivative se jo trigonometric equation milegi usko solve karna kaafi lengthy hai. Conic Section and Probability videos coming soon.
