Re: Sin, Cos, and Tan

Could be time for more trig problems.


In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

Re: Sin, Cos, and Tan

ok so first im gonna pick Sin because im trying to find the opposite and i know the hypotenuse. so the sin equation is Opp/Hyp = Sin(x) now replace the vars and i get Opp/12 = Sin(32) so now i find out what the sin of 32 equals and i get 0.52 now i do 12x0.52 and i get 6.35 now to double check i do 6.35/12 which equals 0.52 now i click sin-¹ so the length from A to B is 6.35 cm big_smile

Re: Sin, Cos, and Tan

hi Aartt,

Very good.  I got 6.35903..... so I rounded up to 6.36 cm.  Take care with the rounding!

Another one below.  Say when you feel you've had enough trig and want to move on.
