ya i know  ;)


 

SGVaibhav:
@T.Q... thanks i understood :D
but at times, it can get more complex...
so
@A.F ..  how did u do it?

It's P1 stuff...we do it in A level

divide the equations...so u get

500/2500 = TAC sin (T)/  TAC cos (T)

sin(T)/cos(T)=Tan (T)
Tan(T)=0.2

I got  equations, and i dont know how to solve them ??

1-       2500 = TAC cos (T)
2-       500 = TAC sin (T)

for those who are confused with TAC, take it as a single variable x......
i dont know how to solve such equations...

Divide both equations by each other:

Tsin(T)/Tcos(T)=500/2500...The tension cancels out..

sin/cos=tan (T)
500/2500=0.2

how about now?

oooooppsss..sory nid..posted in the same time ;D ;D
