Cheers bro, much appreciated. So most of your stories are 'fictional'? I was hoping to do one with a really simple storyline and yet really meaningful but my mind is somewhere else today
1)
Simplify:
2 (cos^2 3x) - 1
2)
Prove following identities:
Sin A + Cos A Tan B =Tan (A+B)
_________________
Cos A - Sin A Tan B
Cheers if you can help
Hey i was wondering if anyone could help me with this physics question:
A battery operated toy car of mass 0.5kg is moving at 5m/s before its speed is increased to 7m/s.
What is the amount of work done by the toy's engine to increase its speed?
Cheers
