Aoa sir, really a great lecture of much use only wamted to ask somethi.g about question 5 part 2 i took cross product of a nd b which woild be perpendicular to both and called it d and then proved it aswell i just wanted to ask if it is ok to do the question that way beacuse it was easier to understand that way please let me knoe soon thank you for this outstanding lecture
Hi i startsd watching u recently the only i thing i have to say is that u teach really well just go a little slower like plz explain things with more details cuz u often miss steps and go directly to answer which make student like me who r weak in maths really confuse😢
Aoa sir exercise 3.2 main hum ny dot product k sth unit vector ni lagay answer main or cross product main hum answer k sth unit vector lga rahr hain ye kia concept h please explain kr dein?boht confuse hu 😢
Wsalam dear student. Let me explain you, dot product is totally scalar quantity, that's why it is also known as scalar product meanwhile cross product of two vectors is again a vector and When we compute the cross product of two vectors A and B, the result is a vector that is perpendicular to both A and B. To indicate the direction of this resultant vector, we introduce the unit vector n, which points in the direction normal to the plane formed by the two vectors. Here's why the unit vector n is important in cross products
Aoa sir Mera maths ka sandup hai 16 dec ko , basically mai aap kay lectures dekhti hoon or practice bhi karti hoon sath sath but still I am not sure kay paper mai iss say similar Q ayein gae to mai solve kar loun gi ya nahi . Aap please koi advise suggest kar dai .Thank you.
Wsalam, very good to hear k ap lectures dekhti hain. First, you not need to worry agr question similar aa bhi gye to ap kr len gi I. A, Secondly FBISE ki recommended book yhi hain so questions isi m se ayen gy. Lekin agr ap apni practice ko strong krna chahti hain to Punjab and KpK math 1st year book se bhi questions solve kren.
Moment of force is perpendicular to both r and F because M= rxF and we know cross product of two vectors is vector perpendicular to both given vectors. We are finding the magnitude of M so that's what we took 90
Sir apse parh ke na Dil mutmaeeen hogya hai 😊 kya parhate Hain ap wah ❤

Sir how i thank u allah ka shukar hai ap humha mil gae otherwise pata ni kia hotah

sry my mistake i just checked d.b is not 0 which means they are nlt perpendicular but can u explain why it would be a great help thankyou
becuase except d.b everything else checks out c.d is 1 and d.a is 0 and d.b is problem
JazzakAllah, see the question again

Sir ap thora uncha bol kare takai hamai samjh sahi aye
Sure I will, dear please use hands free for lecture

Thankyou so much sir
Aap meray liye dua kijye ga kay meray maths mai full marks ayein .Ameen

Aoa sir please aap yeh bata dain kay hamain kesay pata chaly ga [sin (phie by 3) underroot 3/ 2 hai
Means kay calculator per say kaisay pata chaly ga
@@malikgee961 π/3 Is radian angle, radian se degree mai convert kren to
π/3 x 180/π kren gy jis se ap k pas 60° aye ga or sin(60°)=√3/2 hota hai..
@malikgee961 calculator py likhen sin60° =0.8662 aye ga, or √3/2 bhi 0.8662 hota hai... Agr Casio ka calculator h to ap k pas √3/2 he aye ga...

Assalamualaikum sir do you know about reduced syallabus of maths. If you know please tells us
@@talhakhattak264 till, there is no news about reduction of syllabus
2:15:24 sir yahan r = (point F applied) - (point about F) nai ho ga??
@@Patience-u1 no, for further clarification see exercise 7.5 Punjab textbook
2:26:27 yahan angle 90 hi q liya between r and F
@@Patience-u1 see diagram.
