T # 8
If x*sin60°*tan30°=(sin45°*cot45°)/(cos30°*cosec60°), find x.
for this i got every part easily cept sin 45 because it equals a long decimal so it didnt seem right but i got 1.414

Re: Trigonometry
Hi anonimnystefy, Shivamcoder3013, Stormtangent, and fusilli_jerry89,
The solutions #7 and #8 are correct. Excellent!
#9. If two angles of on the base of a triangle are 22.5 degrees and 112.5 degrees, then what is the ratio of the height of the triangle to length of the base?

Hi ganesh;
In mathematics, you don't understand things. You just get used to them.
90% of mathematicians do not understand 90% of currently published mathematics.
I am willing to wager that over 75% of the new words that appeared were nothing more than spelling errors that caught on.
