have you got an example?
Like in the book there is an equation and it says sin 109/RQ=sin39/40 RQ= 40 sin109/sin39 which is about 60.1 cm but when I type it into my calculator I get 33.9
thats equation RQ = is correct
Yeah I know because it's in my book but I keep getting 33.9 and the answer is 60.1???
I type it in just as the equation says.
ok calculators vary in the way you enter data with mine if in enter 40 * sin109 / sin 39 it gives me 60.09
that is seriously exactly what i type into mine? I don't understand hahah
with some calculators you need to add angle first then sin
try 109 then sine
Okay hold on
It says error
ok the sin 109 is the way to go try sin 109 then hit exe
I don't see a button that says exe
well whatever button you use to get a result
Okay I get .8167
or does it give you the answer automatically
well it should be 0.9455
is your calculator set to degrees or radians?
I have no clue how do I find out???
thats the problem!!!
i just set mine to radians and got 0.816
omg, how do I change it to degrees?
what make is ur calculator?
its a TI-84
oh i don't know about those . Mines a Casio - maybe you can find a manual on-line.
Okay, I will do that, you're a life saver I would have never figured that out! haha thank you(:
Okay could you help me with something really quick actually? I just want to make sure I'm doing this right. my first equation I have angle A= 62 degrees a= 30 and b=32. So if I'm trying to find angle B I set it up like Sin62/30=SinB/32 right??
and then it's 32*Sin62/30 ?
Okay but then I get .9418 as my answer?
By the way - i used to have a TI a long way back - i remember you changed degrees to radians and vise versa using the MODE key
Yeah I found a video on how to do it so i fixed that(:
oh ok hold on
sin B = 0.9418 yes
Okay so then is angle B .9418 degrees? I don't get what to do next
no thats the sine of the angle you need the inverse sine on ur calc - its either marked sin-1 or arcsin
Ohh okay, thank you again, I think that's all I needed to know(:
