I am here after my boards. Maths ke lie saari one shot dekhke gaya tha. Bohot achi tyari karai sir aapne Just here to say thankyou sir 🙏🏻🙏🏻🙏🏻 I really appreciate your efforts.
If a line makes angle 90 degree and 60 degree respectively with the positive direction of X andY axis find the angle which makes with the posotive direction of Z axis
as we know cos^2alpha+cos^2 beta+cos^2 gamma=1 then put the value of alpha as 90 ,beta as 60 and solve this equation then you will find the angle gamma made by the Z axis
bhai mera bhi physics exam horrible gaya...100 expect kar raha tha, sirf 95 hi milega.... bro y'all need to stop crying like this and do the work...literally every single video has some mf crying about how their exam went bad...man up
@@user-lh8yl6wl2w if other's success (from hard work) demotivates you then that's an issue I look at successful people and feel inspired and a sense of anger to push myself to get to that position
@@Karthik_Aju Bro sab normal exam k liye mehnat kiye the.. sample paper v aisa nhi aya tha... 🌚 Pahale se pata hota tho jee mains tak ka v padh lete sab... 🥲
@@Rishi.496 Wouldn't worry too much, checking will also be much lenient since paper was on the tougher side lekin phir bhi...they didn't ask anything from JEE topics...They just checked if you had a deep grasp of the topic but ig the phy paper was harder than JEE mains...but don't use it as an excuse bro...learn from this and work harder next time
