how to solve 0 = sin (2x - 3)?
do you have to use a calculator? if so, how?
arcsin(0) = 2x-3
Ok... and then?
solve for x
( arcsin (0) + 3 )/2?
mhm
then what is the answer?
Im sorry Im having a brain block..
Because usually, you'd only have x in the sin's bracket. but now you have an expression inside instead - so how would I simplify/solve?
sin and arcsin find different things, look at your notes if you dont remember what arcsin means
one returns an angle and the other a side
@optiquest ok, I don't actually have notes, but how would I go about Google searching info on arcsin and my original question? (aka what keywords/topic is this? ) thank you!
look up inverse trigonometric functions. if you watch this it would help i think https://www.khanacademy.org/math/trigonometry/unit-circle-trig-func/inverse_trig_functions/v/inverse-trig-functions-arcsin
no I get that; I get the questions where the x in sin (x) is a number and not an expression. But I don't know how to solve my original question...would you be able to solve it with steps? thank you!!
