What no. should logically replace the question mark?
#81 Re: Help Me ! » trigonometry » 2014-07-19 03:52:58
and what about my problem?
#82 Re: Help Me ! » trigonometry » 2014-07-17 04:55:41
what did you do.
the process i used turned out to be very lengthy so i wanted a short one.
#83 Re: Help Me ! » trigonometry » 2014-07-17 04:21:47
I am sorry, I missed a digit.
Now it is correct.
#84 Re: Help Me ! » trigonometry » 2014-07-17 04:08:49
Solve the equation
#85 Re: Help Me ! » trigonometry » 2014-07-05 03:59:13
(silly me.)Yes I meant cos4\theta.
thanks for the correction as well as for the proof.:)

here's another question;
prove that

Two trains travelling with constant speed V towards each other and distance between them is L initially.A bird is flying continueously between them with its speed V'.
1)Find the no. of times bird went to the other train and came back.
2)Find the time after which the trains meet.
I took out the time as L/2V.
Pls tell me about the first part.
#91 Re: Help Me ! » trigonometry » 2014-06-22 02:15:19
hmm, thanks.
#92 Re: Help Me ! » trigonometry » 2014-06-19 15:31:29
Substituting back leads to alpha = 0 or cos(gamma/2) = 1/2.
Bob
i couldn't get this statement.

read it in the newspaper too.
good to here that.
#97 Re: Help Me ! » integration » 2014-06-13 17:31:24
yes i got it.
thanks again.
#98 Re: Help Me ! » integration » 2014-06-12 22:02:06
but the answer given is:-
where C is the integral constant.
and unfortunately I am not able to reach this.
help.
