trigonometry#5A vertical tower stands on a horizontal plane and is surmounted by a flagstaff of height 7 m. At a point on the plane, the angle of elevation of the bottom of the flagstaff is 36° and that of the top of the flagstaff is 45° .Find the height of the tower. friendship is tan 90°. #2 20140208 19:33:13
Re: trigonometry#5I think using a table is okay in this case 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'

Re: trigonometry#5We can do the nested use of this formula 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'

Re: trigonometry#5Hi niharika_kumar, Expand LHS and equate the imaginary parts We can then easily solve it as a quadratic, putting y=sin(x)^2: Hence, and and "Believe nothing, no matter where you read it, or who said it, no matter if I have said it, unless it agrees with your own reason and your own common sense"  Buddha?

Re: trigonometry#5Hi; In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #9 20140209 01:15:00
