A particle is projected with speed \(\sqrt{3} i\cap + j\cap +k\cap\) from the origin. If the highest point of trajectory , the velocity vector makes and angle \(\theta\) with n-axis, then find \(\tan \theta\)
I don't know how to represent i cap
|dw:1349108807115:dw|
Three Co-orDinates...hm......if it is Two Cordinate tanx = vy/vx @highest point of trajectory vertical component of velocity is 0
\[u\sin \theta = 0\]
if this is Two-Cordinate then usinx =0........Since it is a Three Coordinate...) i dont thhink...so...and i have nt studied....Three Coordinate Plane...
hmn no problem. @experimentX @sauravshakya @helder_edwin any ideas?
@Jemurray3 @mukushla @ghazi @ganeshie8
@mathslover what does n axis refer to? this is supposed to be a three dimensional coordinate system
Well the question dont tells this .... I am also confused , also in starting it is written : Treat vertically upward as K|dw:1349109611966:dw|
i mean \[\tan \theta = \frac{ 1 }{ \sqrt3 }\]
You're correct @ghazi but HOW?
see if you consider a three dimensional system check out the spherical coordinate system on google you'll find theta is the angle between x and y axis now \[\tan \theta= \frac{ y }{ x }=\frac{ 1 }{ \sqrt3 }\] x and y are the intercepts
Oh very easy it was, I feel it now. Thanks a ton @ghazi
this is what i was thinking |dw:1349110013381:dw|
@amistre64 nice work, @mathslover this is what i was talking about .....
