@ganeshie8 Trigonometry Help (for those who helped before, these are different types of problems) Problem to be posted in image form.
i know \[\sin2\theta\] becomes \[2\sin \theta \cos \theta \] but im not entirely sure where to go from here.
what exactly are you stuck at..
well i dont really know lol, i just dont know what to do at all
\[\large \sin 2\theta = 2\sin \theta \cos \theta \] \[\large = 2\sin \theta \sqrt{1-\sin^2 \theta }\]
plugin the given \(\sin \theta\) value and simplify
so i came out with the wrong answer and after entering it wrong, it actually tells me to use the Pythagorean Identities to solve
yes what did u get as answer ?
0.4770
im getting 0.7225 http://www.wolframalpha.com/input/?i=2*0.3928sqrt%281-0.3928%5E2%29
hm yours is right, ill work it again and see if i can come out with that
ok
ahh got it!
i did it totally wrong the first time
