Use double angle formula
Factor out cos(t)
can you solve it from here?
Hello everyone, just having some trouble with my assignment.
I had to find the equation for velocity using the equation for vertical displacement so I did. The question asks to find the vertical displacement when the velocity is 0.8 m/s so as you can see I subbed it into the equation above. Problem is, im having trouble solving for 't'.
Can anyone help?... It would be much appreciated.
Ill need a lot of help for calculus so I hope I don't bother these forums!
Mr. Fantastic asked a question. Answer it PLEASE. I'm dying to see the resolution to this problem.
I have a question of my own. Is that the displacement function, or the velocity function? Because if you set the displacement function = 0.8, you made a boo boo.
Find the velocity function by taking the derivative of the displacement function. Set THAT equal to 0.8, solve for t, and then plug that value of t into the displacement funtion. This is what you must do.
Or if you were given the velocity function, find the displacement funtion by integrating the velocity function. Or were you given both functions?
Please post the question so as to eliminate any further confusion.
