5th 2rootpi cos pi ?
Nope 💀
R omega?
Wait which question y'all talking about?
question number 6?
Yes it's R omega
5 karna hai kya? 💀
Yes... Send solutions as well please 🥲
$\frac{dx}{dt}=-R\sin\theta\frac{d\theta}{dt}$
\newline
\ $\frac{dy}{dt}=R\cos\theta\frac{d\theta}{dt}$
YE KESE KRTE AAAAAH

Now differentiate $\theta= \omega t$
\ you get $\frac{d\theta}{dt}=\omega$
Fermat's Last Theorem
@Deleted User 5th part
take u = x^2
then apply chain rule
Now its simple
i did
Ok I'll try that
i didnt get it
$(sin(x^2))' = cos(x^2) . 2xdx$
Fermat's Last Theorem
what part do you not get
2ndthe diffrentiation 💀
?
Differentiate both sides
OHH
constant bahar ajaega
t will become t^0 = 1
nvm mai dtheta/dt ki bat krra
What's wrong here the answer is -ve 2√pi
wait
Abey haa Mai constant soch ke 1 kyu soch Raha tha 💀
yeah cos 180 negative
HOTA HAI
Also wat? How is cos pi -1?
cos is negative in second and third quadrant
cos(90+90) = -sin(90) = -1
huh?
bhai 10th kaise pass ki
HUH?
bhai 10th me ye sab to nahi tha 💀
bhai
for cos theta
0-90 degree: value positive
90-270 degree:value negative
270-360 positive
ye sab kab hua bhai ye konse chapter me hai 💀
Oh maine nahi padhi mai 2nd chapter pe hu
i mean tumhe basic trigonometry nahi krvai physics mei?
aakash orientation ke pehle ch me padhaya hoga (trigo)
hame to padhaya
Nah we just did graph trigo wasnt done wtf
;-;
module hogi to usse hi padhle na bhai kuch zyada nahi hai usme
nahi dia shayad
ha yaar but theek hai is question me bas itna theek hai ki cospi = cos 180 = -1?
yes
ha
ok what about 6th?
solved?
ok ill try it once
gimme 5 mins
6th is just a circle atp $$x^2+y^2=R^2$$
and $\frac{dx}{dt}$ stuff represents the velocity so obviously $$v=R\omega$$
Fermat's Last Theorem
real
dude what i have just started 11th what the hell is this??? i havent even started kinematics 💀
i got it
thanks
