I don't know what you mean by
pie3/2 and by 2/pie 7
do you mean 3pi/2 ? or ???
2/pie 7 is even more confusing.
remember tan(theta) = opposite/ adjacent
so you can form a right-angled triangle in the first quadrant, fill in those two sides, then use Pythagoras to find the hypotenuse.
And cos(theta) = adjacent/hypotenuse
my nswers was 2/pi7 but i ws wrong
you did not answer my question.
What do you mean by 2/pi7 ???
do you mean 2/(7pi) ? or (2/pi)(7) ? or ...
write it as (numerator)/(denominator)
sorry my nswer was 2/(7 pi) but it ws wrong
