Question

tan theta = -4/3 then sin theta =?

Answer 1

tan theta = sin theta / cos theta

Answer 2

yes i found sin theta = -4/3 cos theta

Answer 3

yes !

Answer 4

do u want options

Answer 5

what?

Answer 6

a) -4/5 but not 4/5
b) -4/5 or 4/5
c) 4/5 but not -4/5
d) none of these

Answer 7

\[sin(\theta)=\pm\frac{4}{5}\]

Answer 8

option b if you have no further information

Answer 9

how pls elaborate

Answer 10

ok if you draw a right triangle and think of one angle as theta, then you can visualize tangent as "opposite over adjacent"
label the opposite side 4, the adjacent side 3 and the hypotenuse will be 5 by pythagoras

Answer 11

CAN U TELL ME WITH THE HELP OF FORMULA

Answer 12

ok we have one adjacent side 3 and opposite side 4 yes? then pythagoras tells us \[a^2+b^2=c^2\] where the sides are a and b and c is the hypotenuse.
\[3^2+4^2=9+16=25\] so the hypotenuse is 5

Answer 13

if you think of sine as opposite over hypotenuse then you know \[\sin(x)=\frac{4}{5}\] but you do not know what quadrant you are in so you do not know if sine is positive or negative

Answer 14

I UNDERSTOOD
VERY VERY VERY THANKS TO U
