Consider the fig below
in triangle ABC
------eq1
In triangle
CDE
------eq2
Now use
Replace the value of cosec x from eq1 and cot x from eq2 to get the required value of S
Hi, i got this homework problem i just can't figure out. I'm was given the formula S= sqrt((LD^2)/(L+D)). I must find out how that formula was derived using the basic trig functions (sin,cos,tan, Pythagorean theory, etc...). We where given the diagram below to try and figure this problem out.
any help you guys can give me will be a great help.
thanks very much, that was a great help. the only thing i can't figure out now is how to get rid of the + 1 as i factor to get that formula I need. Is there something I am missing as I factor or does the + 1 go away with Cot^2x when i sub the equation for tanx in for it?
